Which of the following statements is true about the average kinetic energy of the particles of a gas? It is directly proportional to the size of the particles, It is inversely proportional to the size of the particles, It is directly proportional to the temperature of the gas, It is inversely proportional to the temperature of the gas?

The statement that is true is:

The average kinetic energy of the particles of a gas is directly proportional to the temperature of the gas.

Explanation:

The relationship between the kinetic energy of gas particles and temperature can be depicted through Charles law.

According to Charles law, the volume of the gas particles will be directly proportional to temperature when the pressure is kept constant.

As the temperature increases, the kinetic energy of the gas molecules will also increase. The gas particles will start to collide and move with even greater force when the temperature is increased. This will lead to an increase in the volume of the gas.
