33. In a thermodynamic process, pressure of a fixed mass of a gas is changed in such a manner that the gas molecules gives out 20 J of heat and 10 J of work is done on the gas. If the initial internal energy of the gas was 40 J, then the final internal energy will be (a) 30 J (b) 20 J (c) 60 J (d) 40 J Ans. c (5) Read More
