The S.I. unit of specific heat capacity is :
(a) J kg−1 (b) J K−1
(c) J kg−1 K−1 (d) kcal kg−1 ∘C−1
S.I. unit is joule per kilogram per kelvin (Jkg-1K-1).
Hence, option c is correct.
The S.I. unit of specific latent heat is :
(a) cal g−1
(b) cal g−1K−1
(c) J kg−1
(d) J kg−1 K−1
Write the expression for the heat energy Q received by m kg of a substance of specific heat capacity c J kg−1 K−1 when it is heated through △t ∘C.
Calculate the heat capacity and water equivalent of 0.035 kg of copper . Specific heat capacity of copper is 389 JKg-1 k-1 given 1kcal=4185 J.
