Celsius and Kelvin Scales

Temperature is a very important and widely used property of gases.

You learned how Gay-Lussac's gas law shows that, for a gas, pressure increases with increasing temperature.

P/T = k Gay-Lussac's Gas Law

P = pressure, T = temperature, k =a constant

You also learned how Charles' Gas Law shows that for a gas:

Volume increases with increasing temperature

V/T = k – Charles' Gas Law

V = volume, T = temperature, k = a constant

So exactly what is temperature?

Temperature

Temperature is simply a measure of the tendency of matter to give up energy to its surroundings.
