Specific Heat Capacity |
A student is trying to explain specific heat capacity to a friend.
Identify, by placing a tick (✓) next to the correct statements about specific heat capacity.
Statement | (✓) here if the statement is correct |
All substances have the same specific heat capacity. |
|
The heavier the material, the more thermal energy is required to raise its temperature. |
|
The larger the change in temperature, the higher the thermal energy will be required to achieve this change. |
|
Specific heat capacity is mainly used in gases. |
The student is confused about how to explain specific latent heat capacity.
Identify, by circling the best option, the explanations that correctly describe specific latent heat capacity.
The student has three substances, aluminium, copper and water set up for an experiment in his laboratory where the room temperature is initially 20 °C. 500 J of heat energy is applied to each substance.
The temperature of aluminium increases to 30 °C, the temperature of the copper to 25 °C and the water to 100 °C.
Write the numbers 1, 2 and 3 next to the correct substances with 1 being the lowest and 3 being the higher specific heat capacity.
- Aluminium ........
- Copper ........
- Water ........
