When water is heated above 100℃ at sea level or normal pressures, water changes into a gaseous state we call water vapor or steam. It’s also referred to as a phase change.

When liquid water is cooled, it contracts like one would expect until a temperature of approximately 4 degrees Celsius is reached. After that, it expands slightly until it reaches the freezing point, and then when it freezes it expands by approximately 9%.

Explanation: The plateau of the graph tends to rise from -20 to 140 degrees as the ice phase i.e is a solid phase to water liquid phase i.e up to 60 degrees and then it starts to go into the atmosphere in the form of gas and this ina stream from due to the changes in temperature with time being constant.

The heat of fusion of water is unusually high. The heat of fusion is the quantity of heat necessary to change 1 g of a solid to a liquid with no temperature change (Weast, 1964, p. F-44). It is also a latent heat and is sometimes called the latent heat of fusion.

The brain is the first organ to begin to break down, and other organs follow suit. Living bacteria in the body, particularly in the bowels, play a major role in this decomposition process, or putrefaction.

Active dying is the final phase of the dying process. While the pre-active stage lasts for about three weeks, the active stage of dying lasts roughly three days. By definition, actively dying patients are very close to death, and exhibit many signs and symptoms of near-death.

So what do dying people want? In short: truth, touch and time. They want others — family, friends and physicians — to be truthful with them in all respects, whether discussing the disease process, treatment options or personal relationships. They want truth but not at the expense of reassurance and hope.

So, what does it feel like to die? As these studies record, death by cardiac arrest seems to feel either like nothing, or something pleasant and perhaps slightly mystical. The moments before death were not felt to be painful. We don’t know if this would extend to other causes of death, but still, it is reassuring.

It can be intimidating for clinicians to introduce the family to the idea of withdrawing oxygen from the unconscious patient nearing death, as it can feel like “pulling the plug.” We do know that providing oxygen to severely hypoxic patients near the end of life can improve their oxygen levels, but will not likely …

Process. You can live for a long time without eating, but dehydration (lack of fluids) speeds up the dying process. Dying from dehydration is generally not uncomfortable once the initial feelings of thirst subside.

The most commonly prescribed drugs include acetaminophen, haloperidol, lorazepam, morphine, and prochlorperazine, and atropine typically found in an emergency kit when a patient is admitted into a hospice facility.

Common symptoms at the end of life include the following:

• Delirium.
• Feeling very tired.
• Shortness of breath.
• Pain.
• Coughing.
• Constipation.
• Trouble swallowing.
• Rattle sound with breathing.

In 211 cases (7.4%), doctors say they gave drugs or stopped treatment to speed the patient’s death. In 825 cases (28.9%), doctors made a decision on treatment that they knew would probably or certainly hasten death. One in 10 patients asked their doctor to help them die faster.

Does Palliative Care Mean You are Dying? No, palliative care does not mean death. However, palliative care does serve many people with life-threatening or terminal illnesses. But, palliative care also helps patients stay on track with their health care goals.

When someone is no longer taking in any fluid, and if he or she is bedridden (and so needs little fluid) then this person may live as little as a few days or as long as a couple of weeks. In the normal dying process people lose their sense of hunger or thirst.

In most people who are dying, the body’s normal systems start to operate more slowly. The heart beats a little more slowly, or with a little less force, and so blood is moved around the body more slowly. This means the brain and the other organs receive less oxygen than they need, and so they do not function as well.

It is not known how many dying people have such visions and experiences, but research suggests that end of life visions and dreams hold profound meaning for dying people, helping them to come to terms with their dying process. It can often appear that people choose the moment to die.

What not to say to someone who is dying

• Don’t ask ‘How are you?’
• Don’t just focus on their illness.
• Don’t make assumptions.
• Don’t describe them as ‘dying’
• Don’t wait for them to ask.
