Question

define internal kinetic energy

Answer 1

the kinetic energy that occurred internally in a body or a object then it is called internal kinetic energy.
hope it's the required answer....

Answer 2

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]
