Answer:

Because the gas molecules move faster.

Explanation:

Kinetic energy (K.E.) is the energy of motion. It is proportional to the square of a gas molecule's velocity.

#K.E. = 1/2mv^2#

Now gas velocity is related to the gas constant and the molar mass, M:

#v = (3RT)/M#

So as temperature, T, goes up, velocity goes up. According to the first equation, as velocity goes up, K.E. goes up.

Answer:

They are the same thing.

Explanation:

In many fields of study the definition of temperature of an object is the absolute kinetic energy of the molecules of that object.
