Internal energy in room Calculator

Internal energy is typically used in thermodynamics and refers to the total energy contained within a substance due to the motion and interactions of its molecules and atoms. In the context of a gas, such as air, internal energy is related to the kinetic energy of the gas molecules and their potential energy due to intermolecular forces. 

• E represents the internal energy 
• M represents the mass of the air in the room
• e is the specific internal energy of the air
