MCQ
Choose the correct option:
  • A
    Zeroth law gives the concept of temperature.
  • B
    Temperature measures the 'hotness' of the body.
  • C
    Heat flows from higher temperature to lower temperature until thermal equilibrium is attained.
  • D
    All of the above.

Answer

  1. All of the above.

Heat flows from body A to body B because temperature of body A is higher. At thermal equilibrium, $\text{T}_\text{A}'=\text{T}_\text{B}'$

A in equilibrium with C A in equilibrium with B
B in equilibrium with C
