Physics Advanced Level Paper 2 June 2001 Question 1

A 100 g calorimeter contains 300 g of water at room temperature.

50 g of ice is added to this calorimeter and the equilibrium temperature recorded is 282.7 K. Calculate the room temperature. The specific heat capacity of copper = 380 Jkg^-1K^-1, the specific latent heat of fusion of ice

= 3.25 x 10⁵ JK^-1.

Proposed Solution

Heat lost by calorimeter + water = Heat gain by ice in changing state + heat used in warming the melted ic
