Question

derive the expression for molar specific heat capacity​

Answer 1

Answer:

Molar specific heat of a substance is defined as the amount of heat required to raise the temperature of one gram mole of the substance through a unit degree.

By definition, one mole of any substance is a quantity of the substance whose mass in gram is numerically equal to the molecular mass M.

Thus C = Mc …

(i) n → No. of moles m → Mass of substance in grams. i.e., n = mMmM or m = nM From equation (i) c = Δθm(Δt)∆θm(∆t) = ΔθnM(Δt)∆θnM(∆t) M = 1n(ΔθΔt)1n(∆θ∆t) Using equation (i) C = 1n(ΔθΔt)
