1.	State in brief, the meaning of each of the following : (i) The heat capacity of a body is 50 J °C-1 (iii) The specific latent heat of fusion of ice is 336000 J kg-1 . (iii) The specific heat capacity of copper is 0.4 J g-1 °C-1.
Answer» (i) Heat capacity of a body is 50 J/°C → It means 50 joule of heat energy is required to raise the temperature of the body by 1°C. (ii) Amount of heat required to melt one kilogram of ice is 336000 J. (iii) 0.4 J of heat is required to raise the temperature of one gram of copper by 1°C.
