According to KMT, if the temperature of a gas is increased, there will only be a constant pressure if the volume increases. If this occurs, there will be a decrease in the frequency of collisions with the container walls. What gas law is KMT explaining?

The gas law KMT is explaining is Charles' law

Explanation:

The gas law KMT is explaining is Charles' law. Charles' law states that " the volume of a fixed mass of a gas is directly proportional to the temperature provided that the pressure remains constant". This means that, at constant pressure, as the temperature of a gas increases, the volume increases. Also, as the temperature of a gas decreases, the volume decreases.

Mathematically,

V ∝ T (V varies directly with T)

Where V is the volume and T is the temperature.

We can then write that,

V = kT and

V/T = k

This means that

V1/T1 = V2/T2 = V3/T3 ...

Hence,

V1/T1 = V2/T2

This is the Charles' law equation.
