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.
