Question

Calculate the number of kJ of heat necessary to raise the temperature of 60.0 g of aluminium from 35°C to 55°C. Molar heat capacity of Al is 24 J $K^{-1}$ $mol^{-1}$.

Answer 1

The amount of heat required to raise the temperature of 60 grams of aluminium from 35-degree Celsius to 45-degree Celsius can be determined.

The calculation is carried out by multiplying the given mass of aluminium with the difference in temperature and the specific heat capacity of aluminium and it is calculated as follows

Heat required is given by Q and it can be expressed as,

$Q=mC_{p}$ΔT

$=\frac{60\times 24}{27\times (65-36)}$

=1600 J=1.6 KJ
