5. A 3m-cube rigid tank initially contains air at 100kpa and 22C. the tank is connected to a supply line through a valve. Air is flowing in the supply line at 600kpa and 22C. the valve is opened and air is allowed to enter the tank until the pressure in the tank reaches the line pressure at which point the valve is closed. If the final temperature of air in the tank is 80C, determine a.) The mass of air that entered the tank b.) The amount of heat transfer
Kinetic Theory of Gas
The Kinetic Theory of gases is a classical model of gases, according to which gases are composed of molecules/particles that are in random motion. While undergoing this random motion, kinetic energy in molecules can assume random velocity across all directions. It also says that the constituent particles/molecules undergo elastic collision, which means that the total kinetic energy remains constant before and after the collision. The average kinetic energy of the particles also determines the pressure of the gas.
P-V Diagram
A P-V diagram is a very important tool of the branch of physics known as thermodynamics, which is used to analyze the working and hence the efficiency of thermodynamic engines. As the name suggests, it is used to measure the changes in pressure (P) and volume (V) corresponding to the thermodynamic system under study. The P-V diagram is used as an indicator diagram to control the given thermodynamic system.
