Explanation:
The correct answer is option 'D' - Isothermal process.
An isothermal process is a thermodynamic process in which the temperature remains constant throughout the process. In this case, when air is being forced into the tire using a bicycle pump, the slow downward movement of the piston allows the air to enter the tire gradually and uniformly. During this process, the temperature of the air remains constant.
Here is a detailed explanation of why the process can be considered as isothermal:
1. Temperature remains constant:
During the slow downward movement of the piston, the air is being compressed and forced into the tire. However, the process is slow enough that the heat generated due to compression is dissipated to the surroundings, keeping the temperature constant. The heat transfer allows the temperature to remain the same throughout the process.
2. Pressure is constant:
The pressure against which the air is being forced into the tire is given as 4-5 bars. Since the pressure is constant, it implies that the system is in equilibrium with the surroundings. In an isothermal process, the pressure remains constant as long as the temperature remains constant.
3. Work done is proportional to the change in volume:
The work done during the compression process is given by the equation: W = PΔV, where W is the work done, P is the pressure, and ΔV is the change in volume. As the air is being compressed into the tire, the volume decreases. Since the pressure and temperature remain constant, the work done is directly proportional to the change in volume.
4. No heat transfer:
In an isothermal process, there is no heat transfer between the system and the surroundings. This is because the temperature remains constant throughout the process. In the case of the bicycle pump, the slow downward movement of the piston allows for gradual compression of the air without significant heat transfer.
Based on these factors, the process of forcing air into a tire against a pressure of 4-5 bars can be considered an isothermal process. The slow downward movement of the piston ensures a gradual compression of the air, keeping the temperature constant.
