Explanation:
The relationship between volume and temperature at constant pressure is expressed in this statement:
- The relationship is directly proportional; as temperature increases, volume increases in the same way.
The relationship between the volume of a gas and temperature its temperature is defined by Charles Law. This law state that the volume of a given mass of gas is directly proportional to its temperature at constant pressure. It is illustrated mathematically thus:
V ∝ T or
V/T = constant
For example, if a balloon is filled with gas and placed in a cooling van, the nylon will reduce in size. But if it is heated up, the nylon will expand.
Therefore, option B correctly describes the relationship between volume and temperature at constant pressure.
