A gas expands such that its initial and final tempervature are equal. Also the process followed by the gas traces a straight line on the p-v graph. HERE THE TEMPERATURE OF THE GAS FIRST INCREASES THEN DECREASES..HOW..?

  • Since the initial and final temperatures are equal it implies that the process is isothermic. The internal energy is only a function of temperature and hence change in internal energy is equal to zero.
  • Initially there is pressure built up and there is heat transferred to the system and hence the gas temperature first increases and slowly decreases later.

  • Thanks & Regards,
