Answer:

50.6 J

Explanation:

We have to use the formula

H= mcθ

Where

H= quantity of heat absorbed in joules

m= mass of aluminum= 1.5g

c= specific heat capacity of aluminum= 0.75 J/g°C

θ= rise in temperature of aluminum = 45°C

Substituting into H= mcθ

We have ;

H= 1.5g × 0.75 J/g°C × 45°C

H= 50.6 J
