Answer: 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:
[tex]Q= m\times c\times \Delta T[/tex]
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:
[tex]\Delta T={\text{Change in temperature}}=(10-50)^oC=-40^oC[/tex]
[tex]Q=10g\times 0.21Cal/g^oC\times-40^oC[/tex]
Q = -84 Calories
Hence, the amount of heat released is 84 calories.
