Q1. First law of thermodynamics is a special case of

•  Newton's Law
•  Law of conservation of energy
•  Charle's Law
•  Law of heat exchange

Q2. If Î”Q > 0 when heat flows into a system, Î”W > 0 when work is done on the system, then the increase in the internal energy U is

•  Î”W + Î”Q
•  Î”W - Î”Q
•  Î”Q - Î”W
•  -(Î”W + Î”Q)

Q3. In a given process on an ideal gas, dW = 0 and dQ < 0. Then for the gas

•  The temperature will decrease
•  The volume will increase
•  The pressure will remain constant
•  The temperature will increase

Q4. If Î”Q and Î”W represent the heat supplied to the system and the work done on the system respectively, then the first law of thermodynamics can be written as (where Î”U is the internal energy)

•  Î”Q = Î”U + Î”W
•  Î”Q = Î”U - Î”W
•  Î”Q = Î”W - Î”U
•  Î”Q = -Î”W - Î”U

Q5. In thermodynamic process, 200 Joules of heat is given to a gas and 100 Joules of work is also done on it. The change in internal energy of the gas is

•  100 J
•  300 J
•  419 J
•  24 J

Q6. In a thermodynamic process pressure of a fixed mass of a gas is changed in such a manner that the gas releases 20 joules of heat and 8 joules of work was done on the gas. If the initial internal energy of the gas was 30 joules, then the final internal energy will be

•  2 J
•  42 J
•  18 J
•  58 J
