Question

When two objects are placed in thermal contact, and reach equilibrium (A) the internal energy of each is the same (B) the temperature is the same (C) the specific heat is the same (D) more than one of the above (E) none of the above. Explain your answer

Answer 1

B

Step-by-step explanation:

This question pertains to Zeroth Law of thermodynamics which states that whenever two objects with different temperature T_1 and T_2, are brought into thermal contact Heat Transfer takes place due to the differences in temperatures dT = (T_1 - T_2). The exchange of heat brings the Individual temperatures to a weighted mean Temperature T_equilibrium. After this both objects are at the same temperature, Hence NO HEAT TRANSFER. The objects are now said to be thermal equilibrium.
