Question 7

A student investigates the thermal properties of vegetable oil during heating. Table 1 shows the experimental data collected.

Table 1

PropertyValue
mass of vegetable oil0.50 kg
starting temperature of oil15 ∘C15 \text{ }^\circ\text{C}15 ∘C
final temperature of oil95 ∘C95 \text{ }^\circ\text{C}95 ∘C
change in thermal energy of oil80,000 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 energy​
