Matter can be defined or described as anything that takes up space, and it is composed of miniscule particles called atoms. It must display the two properties of mass and volume.

Physical properties: Matter has mass and volume, as demonstrated by this concrete block. You can observe its mass by feeling how heavy it is when you try to pick it up; you can observe its volume by looking at it and noticing its size. Mass and volume are both examples of extensive physical properties.

An object with more mass is pulled by gravity with greater force, so mass and weight are closely related. However, the weight of an object can change if the force of gravity changes, even while the mass of the object remains constant.

density

Physical properties are used to observe and describe matter. Physical properties include: appearance, texture, color, odor, melting point, boiling point, density, solubility, polarity, and many others.

The properties of matter include any traits that can be measured, such as an object’s density, color, mass, volume, length, malleability, melting point, hardness, odor, temperature, and more.

The three basic properties of matter are volume, mass, and shape.

Properties of Matter (Grade 4)

• solid, liquid, and gas.
• buoyancy, mass, shape.
• gas, liquid, and mixture.
• density, weight, and gas.

Physical properties of matter are properties that can be measured or observed without matter changing to an entirely different substance. Examples of physical properties of matter include melting point, color, hardness, state of matter, odor, and boiling point.

physical and chemical properties. Examples of physical properties are: color, smell, freezing point, boiling point, melting point, infra-red spectrum, attraction (paramagnetic) or repulsion (diamagnetic) to magnets, opacity, viscosity and density. There are many more examples.

Examples of chemical properties include flammability, toxicity, acidity, reactivity (many types), and heat of combustion. Iron, for example, combines with oxygen in the presence of water to form rust; chromium does not oxidize (Figure 2).

Hydrogen Properties – What are the Physical Properties of Hydrogen?

• Color : Colorless.
• Phase : Gas : Hydrogen changes from a gas to a liquid at a temperature of -252.77°C (-422.99°F) : It changes from a liquid to a solid at a temperature of -259.2°C (-434.6°F)
• Odor : Hydrogen is an odorless gas.
• Taste : A tasteless gas.

At standard temperature and pressure, hydrogen is a nontoxic, nonmetallic, odorless, tasteless, colorless, and highly combustible diatomic gas with the molecular formula H2. Hydrogen is also prevalent on Earth in the form of chemical compounds such as hydrocarbons and water.

Hydrogen is a colorless gas that is so much lighter than air that it can actually escape the gravitational pull of the earth and shoot off into space. Hydrogen is also the first element on the periodic table and has only on proton and one electron. Hydrogen does not have any neutrons.

Physical Properties of Helium

The main helium source in the world is a series of fields of natural gas in the United States. Helium is a colourless, odourless, insipid and non-toxic gas….Chemical properties of helium – Health effects of helium.

A physical property is a characteristic of matter that is not associated with a change in its chemical composition. Familiar examples of physical properties include density, color, hardness, melting and boiling points, and electrical conductivity.

Lithium has a melting point of 180.54 C, a boiling point of 1342 C, a specific gravity of 0.534 (20 C), and a valence of 1. It is the lightest of the metals, with a density approximately half that of water. Under ordinary conditions, lithium is the least dense of the solid elements.

Lithium and its compounds have several industrial applications, including heat-resistant glass and ceramics, lithium grease lubricants, flux additives for iron, steel and aluminium production, lithium batteries, and lithium-ion batteries.

Fun Lithium Facts

• Lithium is the lightest metal.
• Lithium has the lowest density of any metal.
• Lithium is a shiny, soft metal which reacts violently with water forming a strong corrosive base.
• Lithium burns with a bright red color.
• Lithium is used extensively in rechargeable batteries.

Lithium is a special metal in many ways. It’s light and soft — so soft that it can be cut with a kitchen knife and so low in density that it floats on water. It’s also solid at a wide range of temperatures, with one of the lowest melting points of all metals and a high boiling point.

Stop using lithium and call your doctor right away if you have symptoms of lithium toxicity: muscle weakness, twitching, drowsiness, feeling light-headed, mood changes, blurred vision, ringing in your ears, irregular heartbeats, confusion, slurred speech, clumsiness, trouble breathing, or seizures.

The most important use of lithium is in rechargeable batteries for mobile phones, laptops, digital cameras and electric vehicles. Lithium is also used in some non-rechargeable batteries for things like heart pacemakers, toys and clocks.

It is not known how lithium works to stabilize a person’s mood. However, it does act on the central nervous system. It helps you to have more control over your emotions and helps you cope better with the problems of living.

Long-term Control: The desirable serum lithium levels are 0.6 to 1.2 mEq/l. Dosage will vary from one individual to another, but usually 300 mg of lithium carbonate t.i.d. or q.i.d., will maintain this level.

Substantial affect and mood changes are induced by lithium carbonate. Lethargy, dysphoria, a loss of interest in interacting with others and the environment, and a state of increased mental confusion were reported.

At high doses, lithium reduced their lifespan. “We found low doses not only prolong life but also shield the body from stress and block fat production for flies on a high sugar diet,” said co-researcher Dr Ivana Bjedov from the UCL Cancer Institute.

The researchers’ analysis bore out one of the two main criticisms of lithium, but found the other to be baseless, the report says. They found that patients on lithium had a higher risk of suffering kidney function problems and developing hypothyroidism or hyperthyroidism and also hypercalcemia.

Most people take it for years with no problems. If you’ve been taking lithium for some time, it can cause weight gain. It can also cause problems with your kidneys or thyroid gland. Common signs of an underactive thyroid are tiredness, weight gain and feeling depressed.
