# Problem: A gas in a sealed cylinder is heated from bottom of the cylinder. Which of the following does not increase as the gas is heated?(A) the average number of gas molecules hitting the cylinder walls per second(B) the average kinetic energy of the gas molecules(C) the average speed of the gas molecules(D) the average distance between the gas Molecules

###### FREE Expert Solution

The ideal gas equation:

$\overline{){\mathbf{P}}{\mathbf{V}}{\mathbf{=}}{\mathbf{n}}{\mathbf{R}}{\mathbf{T}}{\mathbf{=}}{\mathbf{NkT}}}$

Here, P is pressure, V is volume, n is the number of moles, R is the universal gas constant, N is the number of molecules, k is Boltzmann constant, and T is temperature.

When the gas is heated, the temperature, T is increased.
