779,247 J is the amount of heat released.
<u>Explanation:</u>
The equation that gives the amount of heat supplied is
Where,
E or Q – amount of heat supplied
m- mass
- specific heat capacity of Aluminium
– temperature variation caused by heat change
The amount of heat energies that causes the temperature to vary or 1 K per kg of the material is known as specific heat capacity (c)
Here, Given data:
– 0.900 J/g.K
To convert gram into kilogram, multiply and divide by , we get
Specific heat capacity of aluminum = 900 J/kg. K
m – 5.89 kg
By substituting the known values in the above equation, we get
