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 0.900 J/(g*K).

779,247 J is the amount of heat released.

Explanation:

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

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)
