Q: In a thermodynamic system the heat balance is achieved when two bodies reach at –
  • A. Even heat energy
  • B. Equal entropy
  • C. The same temperature
  • D. The same molecular energy
Correct Answer: Option C - In a thermodynamic system the heat balance is achieve when two bodies reach at the same temperature. According to Zeroth law of Thermodynamics, when two objects at thermal equilibrium are in contact, there will be no heat transfer between the object. Therefore, they are the same temperature.
C. In a thermodynamic system the heat balance is achieve when two bodies reach at the same temperature. According to Zeroth law of Thermodynamics, when two objects at thermal equilibrium are in contact, there will be no heat transfer between the object. Therefore, they are the same temperature.
