Question

Dimensions of specific heat are
(a) [ML² T⁻² K] (b) [ML² T⁻² K⁻¹]
(c) [ML² T² K⁻¹] (d) [L² T⁻² K⁻¹]

Answer 1

Answer:

The specific heat of a substance (per unit of mass) has dimension L2·Θ−1·T−2, or (L/T)2/Θ. Therefore, the SI unit J/K/kg is equivalent to metre squared per second squared per kelvin (m2 K−1 s−2).
