why does potential energy decrease between the molecules?
i did google it but it isnt very clear
question 12b

Well the trick I learned is

Change in Kinetic Energy = change in temperature

If temperature doesn't change KE won't change

The question also says 'constant thermal release' so energy has to be lost during the time,as no change in temp,no change in KE so other energy we know is Potential energy so PE between molecules changes

Other places my trick works is during latent heat circumstances

100° Water Vapor turns to 100° Water,
energy is being given out but no change in Temp,no change in KE so PE changes (changing the state of material)molecules more closer together

Even in cases like 0° Water to 0° Ice
