How will the average kinetic energy of the molecules in a sample of gas change if the temperature is decreased but the volume of the gas is increased?

The kinetic energy decreases

Explanation:

Firstly, it must be known that temperature is a measure of the average kinetic energy of the molecules. In a situation where there is an increase or decrease of temperature, it is expected that there would be an increase or also a corresponding decrease in the amount of kinetic energy.

In the question above , it was stated that the temperature had been decreased. In this case, it also means the average kinetic energy of the molecules have been decreased too. Increasing the volume is like giving them more space to travel. But this opportunity is left not utilized

- "the choice that is not an indicator of a chemical change is "state of matter changes". more common than not, chemical reactions produce energy in the form of light or heat. along with energy, they also produce a new substance called the product that could be in any state of matter (solid, gas, or liquid)."

it is a good conductor
