Reference: AQA
An abiotic factor measured with a thermometer, usually in degrees Celsius, that affects the rate of enzyme-controlled reactions and the distribution of organisms.
A measure of the average kinetic energy of the gas molecules, so a higher temperature means a higher average speed.
Depends on the average kinetic energy of the particles, so it rises when the particles vibrate or move faster.
The speed of sound in air increases as the temperature rises, so 330 m/s is typical rather than exact.
A measure of the average kinetic energy of the particles, not the total.
A factor that affects enzyme activity and metabolic rate.
