Fundamentals

The volume of a sample of gas is dependent upon the Kelvin temperature of the gas. Increasing the Kelvin temperature increases the volume. The two quantities are directly proportional to one another.

There are three questions in this Question Group. Each question is very similar to one another. The question below is one of the questions.
 

Version 1:
A sample of gas has a constant volume and number of particles. As the Kelvin temperature of the gas sample is increased, the pressure of the gas will _______.
increase
decrease
remain constant
 

How to Think About This Situation

For a sealed, non-rigid container of gas, there is a clear relationship between the volume of the gas and the Kelvin temperature. The relationship is described in the graphic below.  Study the graphic and use it to answer this question.
