(a) Define the boiling point of a liquid.
(b) Describe an experiment to determine the boiling point of small quantity of a liquid.
(c) A piece of copper of mass 300 g at a temperature of 950°C is quickly transferred to a vessel of negligible thermal capacity containing 250 g of water at 25°C. If the final steady temperature of the mixture is 100°C, calculate the mass of the water that will boil away.
[Specific heat capacity of copper = \(4.0 \times10^{2} Jkg^{-1}K^{-1}\); Specific heat capacity of water = \(4.2 \times10^{3} Jkg^{-1} K^{-1}\);Specific latent heat of vaporization of steam = \(2.26 \times10^{6} Jkg^{-1}\)
(d) State four other effects of heat on a substance other than expansion.
