How many joules of heat are needed to raise the temperature of 1.5 g of aluminum at 45°C, if the specific heat of aluminum is 0.75 J/g°C? Group of answer choices

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
