Differentiate between heat and temperature.

What is the international (SI) unit for temperature?

Convert a room temperature of 27 °C to the Kelvin scale.

Define the specific heat capacity of a substance.

Substance A has a high specific heat capacity, and substance B has a low one. If equal masses of both are supplied with the same amount of heat, which one will show a greater temperature increase?

Calculate the heat energy required to raise the temperature of 2 kg of water from 25 °C to 75 °C. (Specific heat capacity of water is 4200 J kg⁻¹ °C⁻¹).

Name the three methods of heat transfer.

Which method of heat transfer is primarily responsible for heat travelling from the Sun to the Earth?

Explain how a sea breeze is formed using the principle of convection.

Why are the handles of cooking pots often made of plastic or wood? This relates to which method of heat transfer?

Define latent heat of fusion.

Explain why, during a change of state (e.g., melting ice), the temperature of the substance remains constant even though heat is being supplied.

Why does a burn from steam at 100 °C cause more severe injury than a burn from boiling water at 100 °C?

Differentiate between evaporation and boiling.

Explain why wearing light-coloured clothing in hot, sunny weather helps to keep you cool.
