Answer:
The kinetic energy decreases
Step-by-step 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
