The energy required to raise the temperature of an iron ball by 1 K is `500 JK^(-1)` . Calculate the amount of energy required to raise its temperature by 20 K.

Explanation

Heat capacity, `C. = Q // DeltaT`
`Q = C. xx DeltaT`
Here , `C. = 500 JK^(-1)`
`Q = 500 xx 20 = 10000 J.`
The amount of heat energy required is 10000 J.
