Answer: (c)

Question : 2

There are four objects A, B, C and D. It is observed that A and B are in thermal equilibrium and C and D are also in thermal equilibrium. However, A and C are not in thermal equilibrium. We can conclude that –

a) B and D cannot be in thermal equilibrium

c) B and D could be in thermal equilibrium but might not be A and D

d) the zeroth law of thermodynamics does not apply here because there are more than three objects

Answer: (a)

Thermal equilibrium means same temperature.

Question : 3

Consider the following statements.

  1. Some bodies may contract from heating
  2. Water shows anomalous expansion.

a) Both (A) and (B) are true.

b) (A) is true and (B) is false

c) (A) is false and (B) is true.

d) Both (A) and (B) are false.

Answer: (a)

Some bodies like wood, rubber etc. have a negative value of the coefficient of thermal expansion, hence they contract on heating.

Hence (A) is true. (B) is also true.
