The Table shows the specific heat capacities of four materials.
Table
| Material | Specific heat capacity in J/kg ∘C\text{J/kg}\ ^{\circ}\text{C}J/kg ∘C |
|---|---|
| water | 4200 |
| aluminium | 900 |
| iron | 450 |
| copper | 390 |
Define the term specific heat capacity.
Which material in the Table needs the most energy to raise the temperature of 1 kg by 1 ∘C1\ ^{\circ}\text{C}1 ∘C?
1 kg of aluminium and 1 kg of copper are each given 9000 J of energy.
Which block has the larger temperature rise? Give a reason for your answer.
State the difference between specific latent heat of fusion and specific latent heat of vaporisation.
