Question

The specific heat of aluminum is 0.892 J/g°C. How much heat(Q) is released when a 10 g piece of

aluminum foil is taken out of the oven and cools from 100° to 50°?
446 J
10.5 J
1.05 J

Answer 1

446 J

Step-by-step explanation:

Use this formula: H = mc⯅θ

where H is heat energy

m is mass of body

c is specific heat (capacity)

⯅θ is the change in temperature I.e T2 - T1

H = mc⯅θ

H = 10 X 0.829 X (100 - 50)

H = 10 X 0.829 X 50

H = 446 J
