(a) A thermometer has a thermal capacity of 1.3 JK-1. The initial temperature of the thermometer is 20°C. When used to measure the temperature of 40 g of water, it measures 37°C. (i) Determine the energy absorbed by the thermometer when it is placed in the water. (ii) Calculate the temperature change of the water as a result of introducing the thermometer. specific heat capacity of water = 4.2 x 103 J kg K-1
