1

What is temperature a measure of?

2

Which of these has the largest total amount of thermal energy?

3

Some energy is transferred to heat some water. Then three times as much water is heated for three times longer. How would the new temperature rise compare?

4

In an experiment to find the specific heat capacity of a metal block, what can be done to reduce experimental error?

5

How much energy is needed to raise the temperature of 0.5 g of lead by 10°C? (Specific heat capacity = 129 J/kg°C)

6

How do the particles in a solid move?

7

What is the energy change when 0.1 kg of molten lead freezes? (Specific latent heat of fusion = 22,400 J/kg)

8

What change of state happens when a substance in the solid state changes to the gas state?

9

How much energy is needed to turn 0.1 kg of oxygen gas into a liquid at the same temperature? (Specific latent heat of vaporisation = 213 kJ/kg)

10

Which part of a heating curve shows the changes of state?
