Question

Jeff has 10 grams of water and 10 grams of vegetable oil in separate containers. Both liquids have a temperature of 24°C. Jeff heats both liquids over a flame for five minutes. When he’s finished, he discovers that the temperature of the oil increased more than the temperature of the water. What can Jeff conclude from this experiment? Vegetable oil is a better conductor of heat than water. Water is a better conductor of heat than vegetable oil. Vegetable oil has a higher heat capacity than water. Vegetable oil has a lower heat capacity than water. Vegetable oil is a good insulator.

Answer 1

I think the answer would be that vegetable oil is a better conductor of heat than water.

Answer 2

Answer: Vegetable oil has a lower heat capacity than water.

Explanation:

Specific heat capacity is the heat required to raise the temperature of 1 g of a substance through $1^0C$.

$q=m\times c\times \Delta T$

q = heat absorbed

m= mass of substance

c= specific heat

$\Delta T$ = change in temperature

As both vegetable oils and water both have same mass and have same initial temperature and absorbed same heat.

As the temperature of the oil increased more than the temperature of the water, it means the specific heat of oil is less than that of water as the heat absorbed is same.
