3.0
moles of an ideal gas with a molar heat capacity at constant volume
of 4.9 cal/(mol·K) and a molar heat capacity at constant pressure
of 6.9 cal/(mol·K) starts at 300 K and is heated at constant
pressure to 320 K, then cooled at constant volume to its original
temperature. How much heat flows into the gas during this two-step
process?
