Question

explain why kinetic energy remains constant during phase change
NEED D ANS ASAP

Answer 1

This is only true if pressure remains constant also. Temperature is a macroscopic quantity of matter which is related to the random motion of particles. For instance, a monatomic gas. It is simply the translational motion (kinetic energy) of the particles. When a substance goes through a phase change, the particles have to be broken (or formed). Therefore, when heating a liquid say, many of the intermolecular forces have to be broken to vaporise the liquid, which takes energy. So when a liquid is heated and it reaches the vaporisation point all the heat going into the liquid is used to break these bonds instead of increasing the energy in the degrees of freedom (eg kinetic energy).

Answer 2

your statement is false 0
it will only be true if pressure remains constant

Answer 3

O.o?

Answer 4

lol from what i read that is his statement xD

Answer 5

you r kinda right, that's what my teacher said but using temp, velovity, kinetic energy
thankx anyway
