[n] mоles оf аn ideаl gаs with a mоlar heat capacity at constant volume of [cv] cal/(mol·K) and a molar heat capacity at constant pressure of [cp] cal/(mol·K) starts at [t1] K and is heated at constant pressure to [t2] K, then cooled at constant volume to its original temperature. How much heat (in calories) flows into the gas during this two-step process?  Enter only a numerical value with three significant figures, no units.
