4. 5. In which of following conditions a real gas would behave ideally? (a) Low pressure and low temperature ha (b) At value of temperature equal to its Boyle's temperature (c) Between its critical temperature and its Boyle's temperature (d) At certain high pressure at which compressibility factor Z 1.00 An ideal gas absorbs Q amount of heat from the surroundings at constant temperature and uses it completely to undergo a change in its state from A to B against a constant external pressure of 1 atm. The value of Q is (as per the figure given). [Given that 1 atm L 0.1 kJ] Air (latm) U 20- Volume 15- (L) 10- 505 5+ B (a) 0.5kJ (b) 0.5kJ (c) - 1kJ (d) 1kJ
