Question

When equal mass of hot water and oil at same temperature are allowed to cool, water cools slower than the oil. Why?

Answer 1

Answer:

it's because of difference in specific heat capacity.

specific heat capacity of water is approximately twice that of oil. and hence takes more time to cool...!!

Answer 2

QUESTION:-

When equal mass of hot water and oil at same temperature are allowed to cool, water cools slower than the oil. Why?

ANSWER:-

• When an equal mass of hot water and oil at the same temperature is allowed to cool, water cools slower than the oil because the rate of heat that flows are specified by the thermal conctance of the pot where both the liquid are put and the difference between the temperature of the liquid and the surrounding. As it is known that the water has a higher specific heat than oil which means that water would have to lose more heat for cooling down as compared to oil so water is expected to cool slower.

• Specific heat is the quantity of heat which is required to raise the temperature of one gram of a substance by one Celsius degree.
