(a) Define specific latent heat of vaporization.

(b) (i) What are renewable energy sources?

(ii) List four renewable energy sources.

(c) Explain why tomatoes keep longer when kept in a moist jute bag in a clay pot.

(d) A box has a volume of 0.28 m\(^3\) and is 70% filled with iron fillings at 25°C. Calculate the:

(i) total mass of the iron fillings;

(ii) energy required to melt 10% of the iron fillings. [Density of iron = 8.00 x 10\(^3\) kgm\(^{-3}\); specific latent heat of fusion of iron = 1.38 x 10\(^5\) Jkg\(^{-1}\), specific heat capacity of iron = 460 Jkg\(^{-1}\) k\(^{-1}\), melting point of iron = 1500°C] 10.
