Answer all questions in the spaces provided.
0 1 A student heats 0.35 kg of water in an insulated container using an electric heater
rated at 800 W. The water starts at 15°C.
0 1 . 1 Calculate the energy required to raise the temperature of the water from 15°C to 85°C.
Specific heat capacity of water = 4200 J kg-1 °C-1
[2 marks]
Energy required=____________________J
0 1 . 2 Calculate the minimum time the heater must be on to achieve this temperature rise.
[2 marks]
Time =________________s

,0 1 . 3 In practice, the water takes longer to reach 85°C than expected.
Suggest one reason for this and explain your answer.
[2 marks]
0 1 . 4 The student continues heating beyond 100°C to convert the water to steam.
Explain, in terms of energy and molecular behaviour, why the temperature remains at
100°C during boiling even though energy is still being supplied.

, 0 2 A fixed mass of ideal gas is enclosed in a container of volume 4.0 x 10-3 m3 at
a pressure of 1.5 x 105 Pa and temperature 300 K.
0 2 . 1 Show that the number of moles of gas present is approximately 0.24 mol.
R = 8.31 J mol-1 K-1
[2 marks]
0 2 . 2 The gas is heated at constant volume to 450 K. Calculate the new pressure.
