ahrayia [7]

Work is equal to the force applied times the displacement. Since you pull the wagon at constant speed this means that there is no acceleration on the wagon as it does not change speed. F=ma. Since a=0, F=0. Therefore no work has been done in this situation

Which statement correctly describes the relationship between the volume of a gas and its temperature, in Kelvin, assuming pressu
nekit [7.7K]

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

Charles's law states that at a constant pressure, the volume of fixed a mass of a gas is directly proportional to its absolute temperature or kelvin temperature.

Mathematically, this law can be written as follows;

V = kT\\\\where;\\k \ \ is \ a \ constant \\\\T \ is \ kelvin \ temperature\\\\V \ is \ the \ volume \ of \ the \ gas

This law explains the direct relationship between Volume of the gas and its Kelvin temperature. That is, as Temperature increases, the volume of the gas increases.

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