The specific latent heat of vapourization of lead is 8.7 × \(10^5 Jkg_1\). This means that 8.7 × \(10^5\) J of thermal energy is required to change
a
a given mass of molten lead to vapour at constant temperature and pressure.
b
1 kg of molten lead to vapour at constant temperature and pressure.
c
1 kg of solid lead to vapour at constant temperature and pressure.
d
1 kg of molten lead to vapour for every degree rise in temperature.
