Solution

The correct option is C
Temperature of A = Temperature of B

If the two bodies that are in contact, have the same temperature then there is no heat transfer between them. Temperature is defined as the measure of kinetic energy of a body. When the temperature of two bodies is same, then there is no transfer of energy from one body to another.

Two metallic objects A and B are brought in contact with each other but no heat transfer occurs between them. What could be the possible reason for this?

Q. Two objects A and B of the same temperature are connected through a pipe. The system is said to be in thermal equilibrium, since there is no heat transfer between them.

Q. Two bodies A and B are brought into contact with one another. The heat flows from A to B then the temperature of A is the temperature of B.

Q. Assertion :It is not possible for a system unaided by an external agency to transfer heat from a body at lower temperature to another at a higher temperature. Reason: It is not possible to violate the 2nd law of thermodynamics.

Q. Two identical bodies are made of a material for which the heat capacity increases with temperature. One of these is held at a temperature of

100^{0} C

while the other one is kept at

0^{0} C

. If the two are brought into contact, then, assuming no heat loss to the environment, the final temperature that they will reach is
