To determine the heat required (Q) to increase the temperature of a substance we can apply the following equation:
[tex]Q=mCp\Delta T[/tex]where,
m is the mass of the substance, 50g
Cp is the specific heat of the substance, 0.386J/g.K
deltaT is the temperature difference, 70K
Now, we have the values we need to calculate the heat required, we replace the known data into the equation:
[tex]Q=50g\times0.385\frac{J}{g.K}\times70K=1347.5J[/tex]The heat required to raise the temperature of 50 g of copper by 70 K will be 1347.5J
