Question

The internal energy of a given mass of gas in a system depends upon?

Answer 1

Internal energy

• Internal energy is the sum of the total energy (like chemical, electrical, mechanical) of the system.
• The symbol for internal energy is U.

Dependence on internal energy

• In an ideal gas, the inter-molecular collisions are assumed to be absent and the collisions are perfectly elastic.
• The internal energy of the given mass of gas only depends on temperature because the gas only has translational kinetic energy.

So, the internal energy of the given mass of gas only depends on temperature.
