Correct option is D
Solution:
From the first law of thermodynamics:
Start with the general form of the first law:
dQ = dU + p dVSubstitute specific heat terms:
dQ = Cv dT + p dV

A classical ideal gas is subjected to a reversible process in which its molar specific heat changes with temperature T as . If the initial temperature and volume are T0 and V0, respectively, and the final volume is 2V0, then the final temperature is
Solution:
From the first law of thermodynamics:
Start with the general form of the first law:
dQ = dU + p dVSubstitute specific heat terms:
dQ = Cv dT + p dV
The following bus schedule is seen at a bus stop located somewhere between town A and town B.
Town A: 00:10, then every 20 minutes
Town B: 00:15, then every 20 minutes
If a person arrives at this bus stop at a random time, the probability that the next bus is for town B is:
The Sankey diagram shows food preferences of males and females. The widths of the bands are proportional to the number of persons opting for a given food item.

Which one of the following is an INCORRECT statement about the food preferences?
A boatman on a bank of a river has to carry a dog, a cat and a container full of milk to the other bank in a boat, one at a time. The cat cannot be left alone with the milk or with the dog on either bank. What is the minimum number of times the boatman has to cross the river to carry all to the other bank?
