C. The heat released when the aluminum is cooled from 70°C to 50°C is -180 J.
<h3>What is Specific heat capacity?</h3>
Specific heat capacity is the quantity of heat needed to raise the temperature per unit mass.
<h3>
Heat released when the aluminum is cooled </h3>
The heat released when the aluminum is cooled from 70°C to 50°C is calculated as follows;
Q = mcΔθ
where;
- m is mass of the aluminum
- c is specific heat capacity
- Δθ is change in temperature
Q = (10)(0.9)(50 - 70)
Q = -180 J
Thus, the heat released when the aluminum is cooled from 70°C to 50°C is -180 J.
