2. Goal of experiment
The goal of this experiment is to compare
specific heat capacities of sunflower oil and
water.
3.
4. Procedure
1. Set the hotplate to 80°C.
2. Fill one of the two identical containers with water and
the second with oil of the same mass. The density of the
oil is lower; therefore the oil has larger volume.
3. Insert the thermometer in both containers.
4. Record the initial temperature of the liquids
5. Place the containers above hotplate and start the
stopwatch.
6. Record the temperature of the liquid every 2 minutes
for 20 minutes.
7. Record any observations.

9. Conclusion
The oil is heated more than water, therefore its
specific heat capacity less than water.

15. Specific heat
The specific heat of petroleum oils can be modeled as
follows
where C is measured in BTU/(lb °F), T is the temperature
in Fahrenheit and d is the specific gravity at 60 °F (16 °C).
In units of kcal/(kg·°C), the formula is:
where the temperature t is in Celsius and d is the specific
gravity at 15 °C.

17. Procedure:
1. Calculate heat capacity (temp must be in °F):
Calculation
1. Take the sample about 50 ml.
2. Measure the temperature of sample in °C.
3. Convert the temperature in °F.
