What is the principle of Calorimetry?
(a) Calculate the heat capacity of a copper vessel of mass 150g if the specific heat capacity of copper is `410 J kg^-1 K^-1`
(b) How much heat energy will be required to increase the temperature of the vessel in part (a) from 25°C to 35°C?
Explain the terms melting ?
Fig 11. 11 shows the variation in temperature with time when some wax cools from the liquid phase to the solid phase.
(i) In which part of the curve, the wax is in liquid phase?
(ii) What does the part QS of the curve represent?
(iii) In which part of the curve, the wax will be the in the liquid as well as solid phase?
(iv) In which part of the curve, the wax is in solid phase?
Write the SI unit of:
(i) Amount of heat
(ii) Heat capacity
(iii) Specific Heat capacity
40 g of ice at -16°C is dropped into water at 0°C, when 4 g of water freezes into ice. If specific heat capacity of ice is 2100 J/kg°C, what will be the latent heat of fusion of ice?
50 g of ice at 0°C is added to 300 g of a liquid at 30°C. What will be the final temperature of the mixture when all the ice has melted? The specific heat capacity of the liquid is 2.65 Jg-1 °C-1 while that of water is 4.2 J g-1 °C-1. Specific latent heat of fusion of ice = 336 Jg-1.
