An ideal gas is under air initial pressure of 2.45 × 10 4 Pa and occupies a volume of 0.20 m 3. The slow addition of 8.4 × 10 3 J of heat to this gas causes it to expand isobarically to a volume of 0.40 m 3. (a) How much work is done by the gas in the process (b) Does the internal energy of the gas change If so, by how much
