As the temperature increases, the gas particles absorb more heat energy. They speed up and move farther away from one another. So the increase in temperature causes an increase in volume.

Air temperatures are measured with mercury-in-glass thermometers shielded from radiation by being enclosed in some form of screen. It is also common to measure air temperature in conjunction with wet bulb temperature using an instrument known as a Psychrometer.

The weight of a book is measured in gram.

Normal body temperature is about 98.6 degrees Fahrenheit (°F) or 37 degrees Celsius (°C). Normal temperature often varies from 1° to 2°F (½° to 1°C). A normal temperature is usually lower in the morning and increases during the day. It reaches its high in the late afternoon or evening.

A fever is a high body temperature. A temperature of up to 38.9°C (102°F) can be helpful because it helps the body fight infection. Most healthy children and adults can tolerate a fever as high as 39.4°C (103°F) to 40°C (104°F) for short periods of time without problems. Children tend to have higher fevers than adults.
