Question

If ΔH = mL, where m is the mass of the body, ΔH is the thermal energy supplied to the body, and L is the latent heat of fusion. The dimensions of L are?
Options
A [MLT⁻²]
B [M⁰L²T⁻²]
Correct Answer
C [ML⁰T⁻²]
D [MLT⁻¹]
Correct Answer

Option B is the correct answer.

Detailed Explanation

ΔH has dimensions of energy [ML²T⁻²]. m has dimensions [M]. So L = ΔH/m has dimensions [ML²T⁻²]/[M] = [L²T⁻²] = [M⁰L²T⁻²].

Hint

Latent heat is energy per unit mass.
