Explanation Introduction: The position of piston in the cylinder containing gas is at half the height of cylinder at thermal equilibrium. The gas molecules present in the cylinder start random motion due to the temperature of the cylinder and undergo frequent collision with the walls, piston and with each other. Option (a) is not suitable because the one end of the cylinder is flash-heated and this does not cause any type of movement of molecules up to the piston, which is situated at half the height of the cylinder. Until the molecules reach the piston, they will lose their energy and unable to push the piston alone. Thus, option (a) is incorrect. When the molecules of gas come into contact with higher temperature, their random movement will increase. This movement causes collision of molecules with each other with higher kinetic energy...

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 dire…

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 v…
