Calculate the internal energy of argon and oxygen.

Calculate the internal energy of hydrogen and nitrogen.

What is internal energy ?

A gas mixture consists of 2.0 moles of oxygen and 4.0 moles of neon at temperature T. Neglecting all vibrational modes, calculate the total internal energy of the system.(Oxygen has two rotational modes.)

Define- Internal energy.

Calculate the mass of : one oxygen atom and oxygen molecule

The internal energy of a system can be changed by

104 kj of work is done on certain volume of a gas. If the gas releases 125 kj of heat, calculate the change in internal energy (in kj) of the gas.

Assertion: If a gas is heated isothennally, then no part of the heat supplied is used to increase the internal energy. Reason: Change in internal energy equals work done on the system.

Calculate the energy of a photon, in joule and eV, in a light of wavelength 5000 overset@A .
