.calculate amount of heat required to rais the temperature of 50 g og copper by 70 K? (specific heat of copper is 0.385 J/g.K.

Sagot :

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
