Solution:
The specific heat capacity of a substance is defined by the relation;
Q = msΔθ
Or, \(s=\frac Q{m\triangle\theta}\) --------- (I)
Where m is the mass and Δθ is the change in the temperature, and Q is the heat energy supplied to the system.
∴ Dimension of Q = [ML2T-2]
Dimension of m = [M]
Dimension θ = [K]
so the dimension of specific heat capacity s is
\(s=\frac{\left[ML^2T^{-2}\right]}{\left[MK\right]}=\left[M^0L^2T^{-2}K^{-1}\right]\)
