Indicate whether each of the following statements about a process in a closed system with a constant volume is always true, false, or true in certain conditions (specify the conditions): Calculate the heat that must be supplied to 0.104 g of Ne(g) at 0.250 atm to raise its temperature from 22.0 degree C to 60.0 defree C at constant pressure and constant volume. Assume that neon behaves as an ideal gas.
