Question

How much heat is required to raise the temperature of 125 grams of water by 10.0 °C? The specific heat of water is 4.184 J/g °C

Answer 1

Given that the temperature , T = 10 deg C and mass of the gas is, m = 125 g.

The specific heat is given as S = 4.184 J/g deg C

To find the heat required, Q.

The formula to find heat required is

$Q=\text{ m}\times S\times T$

Substituting the values in the above formula, we get

$\begin{gathered} Q=125\times4.184\times10 \\ =\text{ 5230 J} \end{gathered}$

Thus, 5230 J heat is required to raise the temperature by 10 deg C.
