How much heat is released as a 5.89 kg block of aluminum cools from 462 °C to 315 °C. The specific heat capacity of aluminum is
aliina [53]

779,247 J is the amount of heat released.

<u>Explanation:</u>

The equation that gives the amount of heat supplied is

                 E \text { or } Q=m \times c_{A l} \times \Delta T

Where,

E or Q – amount of heat supplied

m- mass

c_{A l} - specific heat capacity of Aluminium

\Delta T – temperature variation caused by heat change

The amount of heat energies that causes the temperature to vary 1^{\circ} \mathrm{C} or 1 K per kg of the material is known as specific heat capacity (c)

Here, Given data:

c_{A l}  – 0.900 J/g.K

To convert gram into kilogram, multiply and divide by 10^{3}, we get  

Specific heat capacity of aluminum = 900 J/kg. K

m – 5.89 kg

\Delta T=462^{\circ}-315^{\circ}=147^{\circ} \mathrm{C}

By substituting the known values in the above equation, we get

E \text { or } Q=5.89 \times 900 \times 147=779,247 \mathrm{J}
