- When is air temperature the highest?On average, the time of day when air temperature is the highest is usually about 3 PM, as heat continues to build up after noon. However, after 3 P...
- Why is air temperature lower at night?During the night there is no direct sunlight, so there is more solar energy being lost than absorbed, causing air temperature during the night to b...
- Why does temperature decrease with higher altitude?Temperature decreases at higher altitudes because there is less air exerting pressure than at sea level. According to Gay-Lussac’s law, pressure an...
- When do temperature inversions occur?Temperature inversions occur when the normal heat gradient of the atmosphere—air is warmer near the ground and cooler in the sky—is reversed. A tem...
Temperature. Temperature is how hot or cold something is. Our bodies can feel the difference between something which is hot and something which is cold. To measure temperature more accurately, a thermometer can be used. Thermometers use a temperature scale to record how hot or cold something is.
The degree Celsius is the unit of temperature on the Celsius temperature scale [1] (originally known as the centigrade scale outside Sweden), [2] one of two temperature scales used in the International System of Units (SI), the other being the closely related Kelvin scale.
