Option (a) is the unit of specific latent heat and (c) the unit of heat capacity.
From the same topic and chapter, at a similar level.
Define specific heat capacity and state its SI unit.
Calorimetry
Calculate the heat needed to melt 100 g of ice at 0 °C into water at 0 °C. Take the specific latent heat of fusion of ice as 336 J g−1.
Calorimetry
Why does the temperature of a substance not change while it is melting, even though heat is being supplied?
Calorimetry
Calculate the heat needed to convert 50 g of ice at 0 °C completely into water at 30 °C. Take the latent heat of fusion of ice as 336 J g−1 and the specific heat capacity of water as 4.2 J g−1 K−1.
Calorimetry
Calculate the heat needed to raise the temperature of 200 g of water from 20 °C to 100 °C. Take the specific heat capacity of water as 4200 J kg−1 K−1.
Calorimetry
Why is water used as a coolant in car radiators and in industrial cooling?
