Answer:
26.314KJ
Explanation:
The specific heat capacity formula is : [tex]Q=mc[/tex]Δ[tex]T[/tex], where Q is the heat energy, m is the mass, c is the heat capacity of the material, and delta T is the change in temperature.
We know from the question that m = 386grams and delta T = 100.0°C - 24.0°C = 76.0°C. From a simple search, we know the specific heat capacity of aluminum = 0.897J/g°C (this changes a little bit depends on the website you use, but the value should be very similar). Let's apply the formula:
[tex]Q=mc[/tex]Δ[tex]T[/tex]
[tex]Q = 386g (0.897J/gC)(76.0C)[/tex]
[tex]Q = 26314J[/tex] or [tex]26.314KJ[/tex]
Round according to your teacher's specification (example: significant figures) if needed.
