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.
