# Problem: The pressure of a gas inside a closed, rigid container will increase when the gas temperature increases. The pressure of the gas increases because the(A) density of the gas decreases(B) rate of collisions of gas molecules with the surface increases(C) container expands in size when heated(D) gas molecules bond together to form more massive molecules

###### FREE Expert Solution

The ideal gas equation:

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

From this equation, pressure, P is directly proportional to temperature, T.

When the gas temperature increases, there will be a higher speed of movement of the gas molecules.
