Internal energy is sum of

A

Kinetic energy and potential energy

B

All types of energy of the system

C

Energy of internal system

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
B

Intemal energy is the energy associated with every substance, depending on the chemical nature, temperature, pressure and volume. It is the sum of many types of energies such as translational energy, rotational energy, vibrational energy, electronic energy and bonding energy of the molecule.
`U= U_("trans") + U_("rot") + U_("bonding") + U_("electronic")`
