How level of internal energy defined as heat?
Answers
the quality of being hot; high temperature:
_____________________________________________________________
internal energy :
# The internal energy of a system is the sum of all kinetic and potential energy in a system.
# While a system does not contain 'heat,' it does contain a total amount of energy called internal energy.

Answer:
Internal energy of a system is defined as the sum of
the kinetic energies of the atoms and molecules
belonging to the system, and the potential energies
associated with the interactions between these con-
stituents (atoms and molecules).
[Note: Internal energy does not include the potential
cnergy and kinetic energy of the system as a whole. In the
case of an ideal gas, internal energy is purely kinetic. In
the case of real gases, liquids and solids, intermal energy is
the sum of potential and kinetic energies. For an ideal gas,
internal energy depends on temperature only. In other
cases, internal energy depends on temperature, as well as
on pressure and volume. According to quantum theory,
intermal energy never becomes zero. Even at OK. particles
have energy called zero-point energy]
