Absolute zero, temperature at which a thermodynamic system has the lowest energy. It corresponds to −273.15 °C on the Celsius temperature scale and to −459.67 °F on the Fahrenheit temperature scale.

Common temperatures in the absolute scale are: 0 °C (freezing point of water) = 273.15 K. 233.15K (equal measures in Celsius and Fahrenheit)=-40 Celsius. Triple point of water= 273.16K (equal measure in Celsius) 0.01°c.

The dead star at the center of the Red Spider Nebula has a surface temperature of 250,000 degrees F, which is 25 times the temperature of the Sun’s surface. This white dwarf may, indeed, be the hottest object in the universe.

The colder part of a diffusion (incomplete combustion) flame will be red, transitioning to orange, yellow, and white as the temperature increases as evidenced by changes in the black-body radiation spectrum. For a given flame’s region, the closer to white on this scale, the hotter that section of the flame is.

As things heat up and combustion becomes more complete, flames turn from red to orange, yellow and blue. And purple color is combination of red & blue color it means that blue fire is more hotter than purple fire. At hotter temperatures, the flame color moves into the blue-violet end of the visible spectrum.

Potassium salts produce a characteristic purple or violet color in a flame.

Purple is associated with the presence of potassium (K). That’s because cream of tartar is a potassium salt. These element-specific colors are catalogued in an emission spectrum. In that downward transition, energy is released as a photon of light at a specific wavelength of color.

Strontium chloride imparts a bright red color to a flame. A scarlet-red color is imparted to the flame by strontium chloride. The color is brighter red than the lithium flame color. Metal ions combine with electrons in the flame and the metal atoms are raised to excited states because of the high flame temperature.

Lithium burns red because the carmine-red color is imparted by lithium chloride, the color imparted by lithium is less intense than strontium flame color.

Because each element has an exactly defined line emission spectrum, scientists are able to identify them by the color of flame they produce. For example, copper produces a blue flame, lithium and strontium a red flame, calcium an orange flame, sodium a yellow flame, and barium a green flame.

Absolute zero is the lowest possible temperature where nothing could be colder and no heat energy remains in a substance. By international agreement, absolute zero is defined as precisely; 0 K on the Kelvin scale, which is a thermodynamic (absolute) temperature scale; and –273.15 degrees Celsius on the Celsius scale.

The most widely used absolute temperature scale is the Kelvin, symbolized with a capital K, which uses Celsius-scaled degrees (there’s another one, the Rankine, which is related to the Fahrenheit scale). We write temperatures in kelvins without the degree symbol; absolute zero is 0 K.

At zero kelvin (minus 273 degrees Celsius) the particles stop moving and all disorder disappears. Thus, nothing can be colder than absolute zero on the Kelvin scale. Physicists have now created an atomic gas in the laboratory that nonetheless has negative Kelvin values.

Hypothermia can happen in minutes Hypothermia can develop in as little as five minutes in temperatures of minus 50 degrees Fahrenheit if you’re not dressed properly and have exposed skin, especially the scalp, hands, fingers, and face, Glatter explained. At 30 below zero, hypothermia can set in in about 10 minutes.

At 82 F (28 C) you can lose consciousness. Below 70 F (21 C), you are said to have profound hypothermia and death can occur, Sawka said.

Hypothermia can occur when you are exposed to cold air, water, wind, or rain. Your body temperature can drop to a low level at temperatures of 50°F (10°C) or higher in wet and windy weather, or if you are in 60°F (16°C) to 70°F (21°C) water.

Humans freeze to death when their internal body temperature drops below 70 degrees. It’s possible to freeze to death in 40 degree temperatures, but that’s rare. The amount of time you can survive in the cold drops along with the temperature. Most of the boundaries that humans can survive are well known.

Normal body temperature is 98.6°F. You have hypothermia if your body temperature drops below 95°F. Hypothermia also can occur in temperatures that are not bitterly cold, like those above 40°F. This is usually due to a person being wet, sweaty, or trapped in cold water.

Lay the person on a warm surface (blanket or bed) Provide warm, sweet liquids (avoid coffee, alcohol) Use warm, dry compress (only on the neck, chest wall, or groin and not on the arms or legs) Do not apply direct heat (no hot water or placing a hot-water bag on the person’s body)

However, for most people, a temperature of 96 is not normal. It could be an error with your thermometer. In some cases, a low temperature could mean you’re experiencing a serious condition called shock. A temperature of 96 degrees F doesn’t necessarily mean you’re sick.

If you have a body temperature of 96, you don’t necessarily need to worry. Although low body temperature is associated with several health risks, in some cases, a temperature of 96 is a normal fluctuation of the body’s temperature.

When you have an infection, your body’s temperature usually rises as it tries to fight off the bug causing the infection. Interestingly, some people see their body temperature go down (hypothermia) instead of up. This is why any change, high or low, can be a sign of sepsis.

If your core body temperature dips down to 95 F (35 C) or lower, that’s considered hypothermia. It’s often caused by exposure to cold weather, but there are other factors that can put you at risk for hypothermia, such as age and certain medications.

When your body temperature drops, your heart, nervous system and other organs can’t work normally. Left untreated, hypothermia can lead to complete failure of your heart and respiratory system and eventually to death. Hypothermia is often caused by exposure to cold weather or immersion in cold water.

These can include:

• feeling dizzy or faint.
• a change in mental state – such as confusion or disorientation.
• diarrhoea.
• nausea and vomiting.
• slurred speech.
• severe muscle pain.
• severe breathlessness.
• less urine production than normal – for example, not urinating for a day.

Patients with severe sepsis have a high ongoing mortality after severe sepsis with only 61% surviving five years. They also have a significantly lower physical QOL compared to the population norm but mental QOL scores were only slightly below population norms up to five years after severe sepsis.

There are three stages of sepsis: sepsis, severe sepsis, and septic shock.

Systolic B.P ≤ 90 mmHg (or drop >40 from normal) Heart rate > 130 per minute. Respiratory rate ≥ 25 per minute. Needs oxygen to keep SpO2 ≥92% Non-blanching rash, mottled/ ashen/ cyanotic.

People with sepsis often develop a hemorrhagic rash—a cluster of tiny blood spots that look like pinpricks in the skin. If untreated, these gradually get bigger and begin to look like fresh bruises. These bruises then join together to form larger areas of purple skin damage and discoloration.

The components of the sepsis 6 are: blood cultures, check full blood count and lactate, IV fluid challenge, IV antibiotics, monitor urine output and give oxygen.

Some patients who have sepsis develop a rash on their skin. The rash may be a reddish discoloration or small dark red dots seen throughout the body. Those with sepsis may also develop pain in the joints of the wrists, elbows, back, hips, knees, and ankles.

Sepsis is a bigger killer than heart attacks, lung cancer or breast cancer. Sepsis is a bigger killer than heart attacks, lung cancer or breast cancer. The blood infection is a fast killer too.

A patient with sepsis might have one or more of the following signs or symptoms:

1. High heart rate or low blood pressure.
2. Fever, shivering, or feeling very cold.
3. Confusion or disorientation.
4. Shortness of breath.
5. Extreme pain or discomfort.
6. Clammy or sweaty skin.

Sepsis happens when an infection you already have triggers a chain reaction throughout your body. Without timely treatment, sepsis can rapidly lead to tissue damage, organ failure, and death. Almost any type of infection can lead to sepsis.

The world’s last line of defense against disease-causing bacteria just got a new warrior: vancomycin 3.0.

Some of the most frequently isolated bacteria in sepsis are Staphylococcus aureus (S. aureus), Streptococcus pyogenes (S. pyogenes), Klebsiella spp., Escherichia coli (E. coli), and Pseudomonas aeruginosa (P.

Sepsis is a serious medical condition caused by the body’s response to an infection. Bacterial infections are the most common cause of sepsis.
