The specific heat capacity of a metal is `160 "J Kg"^(-1)K^(-1)` . Calculate the amount of heat energy required to raise the temperature of 500 gram of the metal from `125^@ C" to " 325^@ C.`

Explanation

Specific heat capacity, `C = Q //m xx DeltaT`
`Q = C xx m xx DeltaT`
`m= 500 g = 0.5 kg`
`DeltaT = 325^@C – 125^@C = 200^@ C = 200 K`
`= 160 xx 0.5 xx 200 = 16000 J.`
The amount of heat energy required is 16000 J.
