A student investigates the thermal properties of vegetable oil during heating. Table 1 shows the experimental data collected.
Table 1
| Property | Value |
|---|---|
| mass of vegetable oil | 0.50 kg |
| starting temperature of oil | 15 ∘C15 \text{ }^\circ\text{C}15 ∘C |
| final temperature of oil | 95 ∘C95 \text{ }^\circ\text{C}95 ∘C |
| change in thermal energy of oil | 80,000 J80,000 \text{ J}80,000 J |
Using data from Table 1, calculate the specific heat capacity of the vegetable oil.
Use the equation:
specific heat capacity=change in thermal energymass×increase in temperature \text{specific heat capacity} = \frac{\text{change in thermal energy}}{\text{mass} \times \text{increase in temperature}} specific heat capacity=mass×increase in temperaturechange in thermal energy36 exam-style questions on Edexcel GCSE Physics 14.2 Specific heat capacity and latent heat. Each one has a worked solution and a mark scheme showing where the marks go.
