A family leaves for summer vacation by driving on the highway. The car tires start the trip with a pressure of 2.5 atm at a temperature of 20 0 C and a volume of 2.1 L. Suggest the preferable pressure of the tire if the volume decreased to 1.4 L after driving, if the temperature of tire gas increases to 1080 C. After some time, he stops the car and put some water in the car radiator since it gets heated. Analyze and Justify your answer for usage of water in radiator to cool the system.
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.
