Two perfectly insulated gas canisters contain air with a specific heat capacity of 1005 J/kg•°C and a density of 1.35 kg/m.One cylinder contains 25 L of air at a temperature of 35°C and the other contains 15 L of air at a temperature of 45°C. The canisters are connected and the gas in both is allowed to come to an equilibrium temperature. Find the equilibrium temperature to three significant figures.

First law of Thermodynamics

The word thermodynamics consists of two words: thermo- and dynamics. Dynamics means the study of motion. The field of thermodynamics is all about the study of the movement of heat. In a more meaningful way, it is stated as the study of the transfer of energy. Energy transfer is something that we encounter in day-to-day life. Automobiles, chemical reactions, refrigerators, and power generators work on the basis of thermodynamic principles.
