The specific heat capacity of a metal is

$160$

$JKg^{-1}K^{-1}$ . Calculate the amount of heat energy required to raise the temperature of

$500\ gram$ of the metal from

$125\ °C$ to

$325\ °C$ .

From the given data,

Temperature of metal before energy supply (T1)

$=$

$125\ °C$

Temperature of metal after energy supply (T2)

$=$

$325\ °C$

Mass (

$m$ )

$=$

$500\ gram$

$=$

$Kg$

Specific heat Capacity (\C\))

$=$

$160$

$JKg^{-1}K^{-1}$

We know that,

Specific heat capacity is,

Formula to calculate Heat transfer (

$Q$ ) is,

Substitute the values,

Amount of heat energy required

$=$
