(i) Calorimetry: meaning, specific heat capacity; principle of method of mixtures; Numerical Problems on specific heat capacity using heat loss and gain and the method of mixtures.
Heat and its units (calorie, joule), temperature and its units (Ā°C, K); thermal (heat) capacity C' = Q/ĪT... (SI unit of C'): Specific heat Capacity C = Q/mĪT (SI unit of C) Mutual relation between Heat Capacity and Specific Heat capacity, values of C for some common substances (ice, water and copper). Principle of method of mixtures including mathematical statement. Natural phenomenon involving specific heat. Consequences of high specific heat of water. [Simple numerical problems].
(ii) Latent heat; loss and gain of heat involving change of state for fusion only.
Change of phase (state); heating curve for water; latent heat; specific latent heat of fusion (SI unit). Simple numerical problems. Common physical phenomena involving latent heat of fusion.
