(a)(i) Mention two modes of heat transfer other than convection.
(ii) Explain land and sea breezes.~(b) An iron rod of length 30cm is heated through 50 kelvin. Calculate its increase in length. (linear expansivity of iron = 1.2 x 10\(^{-5}\)K\(^{-1}\)
(c) An electric heater immersed in some water raises the temperature of the water from 40°C to 100°C in 6 minutes. After another 25 minutes, it is noticed that half the water has boiled away. Neglecting heat losses to the surrounding, calculate the specific latent heat of vaporisation of water.~(c) An electric heater immersed in some water raises the temperature of the water from 40°C to 100°C in 6 minutes.
