you'll need the specific heat capacity of aluminium to solve this question.
H=(0.005)(37-22)(specific heat capacity of aluminium)

Answer: 67.65 Joules

Explanation:

[tex]Q= m\times c\times \Delta T[/tex]

Q= heat gained

m= mass of the substance = 5.0 g

c = heat capacity of aluminium = 0.902 J/g ° C      

[tex]\Delta T={\text{Change in temperature}}=(37-22)^oC=15^0C[/tex]  

[tex]Q=5.0g\times 0.902J/g^oC\times 15^oC[/tex]

Q= 67.65 Joules

Thus heat gained by 5.0 g of aluminum is = 67.65 Joules
