H2 Physics · JC 2 · Medium · Internal energy
A fixed mass of ideal gas is heated at constant volume from 280 K to 340 K. Its initial internal energy is 4.2 × 10 J. For an ideal gas, internal energy U is directly proportional to temperature T. What is the final internal energy of the gas?
- 5.1 × 10 J
- 4.2 × 10 J
- 3.5 × 10 J
- 6.3 × 10 J
