19.25 Heat Q flows into a monatomic ideal gas, and the volume increases wile the pressure is kept constant. What fraction of the heat energy is used to do the expansion work of the gas?

19.26 When a quantity of monatomic ideal gas expands at a constant pressure of 4x104 Pa, the volume of the gas increases from 2x10-3 m3 to 8x10-3 m3. What is the change in the internal energy of the gas?
