City Guilds Model Questions Vol1 2017 Engineering Question 2
Practice practical question 2 from the 2017 City Guilds Model Questions Vol1 Engineering examination. This question covers Calorimetry, Specific heat capacity, Error analysis .
A calorimetry experiment is carried out to determine the specific heat capacity of water. The apparatus consists of a 200 g sample of water placed in an insulated container. The initial temperature of the water is 20.0 °C. An electric heater (voltage 12.0 V, current 2.0 A) is immersed in the water and operated for 300 s. After heating, the water temperature rises to 45.0 °C. Assuming that all electrical energy supplied is absorbed by the water, determine: a) The heat gained by the water (in joules). b) The experimental specific heat capacity (c) of water in J kg⁻¹ K⁻¹. c) Identify two likely sources of error in the experiment and suggest a practical method to minimise each error.
