The piece of metal is heated in boiling water until t has reached the temperature of the water. It is then transferred rapidly to some water in a well-insulated cup. A very sensitive thermometer is used to measure the initial and final temperatures of the water in the cup.
specific heat capacity of water = 4200 J/(kgK)
The readings from the experiment are as follows.
mass metal = 0.050 kg
mass of water in cup = 0.200 kg initial temperature of water in cup = 21.1°C
final temperature of water in cup = 22.9°C
(i) Calculate the temperature rise of the water in the cup and the temperature fall of
the piece of metal.
temperature rise of water =
temperature fall of metal =
[1]
(ii) Calculate the thermal energy gained by the water in the cup. State the equation that you use.
thermal energy gained =
