NEET Physics QUESTION #7228
Question 1

The dimensional formula of $\Delta Q$, the heat supplied to a system, is:

  • $M^1L^2T^{-2}$✔️
  • $M^1L^1T^{-2}$
  • $M^1L^2T^{-1}$
  • $ML^1T^{-1}$
Correct Answer Explanation

Heat is a form of energy. Therefore its dimensional formula is the same as that of energy (work).

$[\Delta Q] = [W] = [Fd] = MLT^{-2} \cdot L = ML^2T^{-2}$
