Answer:
The 150 g Al will reach a higher temperature.
Explanation:
- The amount of heat added to a substance (Q) can be calculated from the relation:
Q = m.c.ΔT.
where, Q is the amount of heat added,
m is the mass of the substance,
c is the specific heat of the substance,
ΔT is the temperature difference (final T - initial T).
<em>Since, Q and c is constant, ΔT will depend only on the mass of the substance (m).</em>
∵ ΔT is inversely proportional to the mass of the substance.
∴ The piece with the lowest mass (150.0 g) will reach a higher temperature than that of a higher mass (250.0 g).
<em>So, the right choice is</em>: The 150 g Al will reach a higher temperature.
