mary and ron are discussing what happens to the kinetic energy of molecules in a liquid as the liquid cools. mary says it decreases. ron says it stays the same. who is correct and why?

mary is correct because molecules are constantly losing kinetic energy no matter what state they are in.

mary is correct because as the liquid cools, the molecules slow down as they lose kinetic energy.

ron is correct because kinetic energy is a fixed characteristic of molecules and does not change.

ron is correct because kinetic energy can only increase, not decrease.

Mary is correct because as the liquid cools, the molecules slow down as they lose kinetic energy.

Explanation:

The way to identify the temperature of a body, according to common sense, is to use the words hot and cold, but in fact, hot is when the molecules are very agitated, causing an increase in body temperature. The cold is related to the more stationary state of the molecules, the less agitated, the colder the body becomes.

With that, we can say that as the liquid cools, the molecules move less and less, which decreases their kinetic energy, which is the energy related to movement. In this case, Mary is correct because, as the liquid cools, the molecules slow down as they lose kinetic energy.

i dont know but

explanation:

whoever your teacher is, deserves a raise for using pokemon as an example

pe = weightxheight = 2000x1000=2,000,000joules
