A cylinder is fitted with frictionless floating piston oriented horizontally with gravity and contained 24.5 L of air at 25oC and 1 bar. The system is then heated to 250oC. If the heat capacity at constant volume (Cv) is 5R/2, calculate the heat that added to the system when the kinetic energy, potential energy and shaft work are negligible.

A cylinder if fitted with a floating piston oriented horizontally (the gas is the system and by having a floating piston it maintains constant pressure). It contains 26.0 L of argon at 30.0C and 1 bar pressure. The system is then heated to 300.0C. Argon can be considered a monatomic gas and therefore would have a Cv = 3R/2, where R is the ideal gas constant. Also for gases Cp = Cv +R. (pay attention to the units). If you...
