Question

How much heat is needed to raise the temperature of a 5.0 gram block of aluminum from 22.0°c to 37.0°c?

Answer 1

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

Answer 2

Answer: 67.65 Joules

Explanation:

`Q= m* c* \Delta T`

Q= heat gained

m= mass of the substance = 5.0 g

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

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

`Q=5.0g* 0.902J/g^oC* 15^oC`

Q= 67.65 Joules

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