First law of thermodynamics

H2 Physics · JC 2 · Medium · First law of thermodynamics

An ideal gas is compressed at constant volume. During the process,

450\,\text{J}

of thermal energy is transferred to the gas and

120\,\text{J}

of work is done on the gas. Using the first law of thermodynamics in the form

\Delta U = q + w

, calculate the change in internal energy of the gas.
