Heat and Energy
qEnergy is the capacity
to do work.
qHeat is one form of energy.
qHeat is one form of internal energy which is associated with the random, disordered motion of molecules and atoms.
qInternal
kinetic/potential energy are different
from the macroscopic kinetic/potential energy.
water
no macroscopic kinetic/potential energy
internal
kinetic energy
(related to temperature)
internal potential energy
(related to the phase)
