Molar heat capacity at constant volume and pressure
When 117 J of energy is supplied as heat to 2.00 moles of an ideal gas at constant pressure, the temperature rises by 2.00 K. calculate the molar heat capacity at constant pressure and the molar heat capacity at constant volume for the gas. is the gas monatomic or diatomic?
Finding heat and work energy transferred from a fluid under pressure.
A cylinder contains .014 cubic metres of a fluid at 700kpa, having a specific enthalpy of 695kj/kg and a specific volume of .00125 cubic metres per kg. Heat energy is supplied until the volume of the fluid becomes .28cubic metres, the pressure remains constant at 700kpa. If the final specific internal energy of the fluid is 885k
Change in internal energy of a system, the environment.
A system does 164 J of work on its environment and gains 77 J of heat in the process. Find the change in the internal energy of (a) the system (b) the environment
