1. A 200 g mass of copper is heated for 40 s by a heater that produces 3000 J/min.

The specific heat capacity of copper is 400 J/(kg K).

What is the rise in temperature?

2. The specific latent heat of vaporization of water is about 6.7 times than that of the specific latent heat of fusion of water. What is the ratio of the latent heat of vaporization of 6.7 kg of water compared to the latent heat of fusion of 1 kg of water?

3. Many gas appliances such as ovens and heaters use a small flame to ignite the main burner.

In order to make sure that the small flame is burning, a temperature-measuring device is inserted into the flame.

What is the most suitable device to use?

4. A new liquid is tested to decide whether it is suitable for use in a liquid-in-glass thermometer.

It is found that the liquid does not expand uniformly with temperature.

What will be the effect of this on the scale of the thermometer?

5. In very cold weather, ice can form on the surface of puddles of water because the air temperature is below that of the water. If the ice layer is found to be thickening at its lower surface, then most of the transfer of energy must be by:

6. A student is given a thermometer that reads $1^{\circ}C$ in pure melting ice and $101^{\circ}C$ in pure boiling water. She uses it to measure the temperature of some water before and after it is heated.

The increase in temperature of the water calculated from her results is

7. A hot liquid is poured into a beaker. The graph shows how the temperature of the liquid changes as it cools towards room temperature.

What is occurring at region X?

8. In an oil refinery, petrol storage tanks are painted with light colour to reduce

9. In a Brownian motion experiment involving smoke particles in air, heavy smoke particles settle quickly but very small smoke particles remain suspended for long periods of time.

Which statement explains why the small smoke particles do not settle?

10. Which of the following temperature is NOT possible?
