Question

Which of the following has the greatest heat capacity?

a. 1,000 g of water
b. 1,000 g of steel
c. 1 g of water
d. 1 g of steel

Answer 1

1000 g of water

The answer is A

Answer 2

Answer: a. 1,000 g of water

Explanation:

Heat capacity is defined as the amount of heat required to raise the temperature of a substance through 1 degree Celsius.

`Q= m* c* \Delta T`

Q= heat gained

m= mass of the substance

c = heat capacity

Heat capacity of water =
`4.186 J/gram^0C`

Heat capacity of steel =
`0.49 J/gram^0C`

Hence 1,000 g of water will have greatest heat capacity.
