I need help understanding which heat equation and which specific heat I need to use in this situation. I know we can have specific heat per mol and per kg.

02 Two insulated cylinders Aand B with volumes VA 28 m3 and V8 5.0 m3 contain chlorine gas at different pressures and temperatures. The cylinders are insulated (no heat is lost to or gained from the outside) and connected by a valve. Initially, the valve is closed and the gas in the two cylinders has the following values: Pa = 4.0 x 105 N/m2, TA=220 K, PB = 2.5 × 105 N/m2 s 520 K. The valve is opened to allow the contents in the two cylinders to mix until the pressure equalizes. valve (a) Assuming there is no change in the temperatures of the containers themselves, determine the final temperature of the gas in the two cylinders. The atomic mass of chlorine gas is 35.4527 u._K

    Consider a solid body having mass m, volume V, density = 10000 kg/m3 , specific heat capacity at constant pressure Cp = 600 J/(kg.K), and its initial temperature Ti = 200oC. Assume the system losses heat to the environment by convection at temperature T = 40oC and heat transfer coefficient h = 12 W/(m2 .K). (a) Start with applying the energy balance, and use the concept of the simplified lumped system analysis to derive an expression for the change of...
