The equation from which heat can be calculated is represented as:
q=mc\Delta T
Where, q=Heat (J)
m=mass of aluminium(g)
Delta T=Change in temperature(⁰C)
c=specific heat (J/g ⁰C)
Here ,
m=mass of aluminium(g)=0.3 g
Delta T=Change in temperature(⁰C)=150-30⁰C=120⁰C
c=0.9J/gC
Putting all the values in the above equation,
q=mc\Delta T
q=0.3×0.9×120
q=32.4 J
So, heat required will be 32.4 J.
