Process: Compression process in a closed system
Explanation:
Compression process: The compression process involves reducing the volume of a gas in a closed system, resulting in an increase in pressure and temperature. This process is widely used in various applications, including gas turbines, refrigeration systems, and internal combustion engines.
Conversion of thermal energy to internal energy: During the compression process, work is done on the gas, causing the gas molecules to collide more frequently and with higher energy. This increased collision frequency and energy lead to an increase in the internal energy of the gas. The conversion of thermal energy to internal energy occurs due to the compression work done on the gas.
Gas temperature increase: As the gas molecules gain more energy through collisions, the average kinetic energy of the gas molecules increases. According to the ideal gas law, the temperature of a gas is directly proportional to its average kinetic energy. Therefore, the increase in internal energy results in an increase in gas temperature.
