\the specific heat of aluminum is 0.21 cal g°c . how much heat is released when a 10 gram piece of aluminum foil is taken out of the oven and cools from 50 to 10 °c?

The amount of heat released is 84 calories.

Explanation:

The equation used to calculate the amount of heat released or absorbed, we use the equation:

where,

Q = heat gained  or released = ? Cal

m = mass of the substance = 10g

c = specific heat of aluminium = 0.21 Cal/g ° C

Putting values in above equation, we get:

Q = -84 Calories

Hence, the amount of heat released is 84 calories.
