Answer 1

Answer #1

According to 1st law of thermodynamics,

Total Heat change is equal to the sum of change in Internal Energy and Work done ,i.e ,

dQ = dU + PdV where PdV = Work done.

Hence, option (d) is correct.

Suppose the work done to compress a gas is 100 J. If 70 J of heat is lost in the process, what is the change in the internal energy of the gas? Hint: Use the first law of thermodynamics. The internal energy of a system changes due to heat (Q) and work (W): U=Q-W. The change in internal energy is equivalent to the difference between the heat added to the system and the work done by the system. Think if...
