Question

Which statement correctly describes the relationship between the volume of a gas and its temperature, in Kelvin, assuming pressure is held constant?
The relationship is inversely proportional; as temperature increases, volume increases in the same way.
The relationship is inversely proportional; as temperature increases, volume increases in the same way.

The relationship is directly proportional; as temperature increases, volume increases in the same way.
The relationship is directly proportional; as temperature increases, volume increases in the same way.

The relationship is directly proportional; as temperature increases, volume decreases in the same way.
The relationship is directly proportional; as temperature increases, volume decreases in the same way.

The relationship is inversely proportional; as temperature increases, volume decreases in the same way.
The relationship is inversely proportional; as temperature increases, volume decreases in the same way.

Answer 1

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.
