Chapter 12, Problem 65A

To determine

The metal which would melt more ice.

Answer to Problem 65A

Aluminum

Explanation of Solution

Introduction:

Thermal energy can be obtained by:

  $Q=mc\Delta T$

Where, m is the mass, c is the specific heat capacity and $\Delta T$ is the difference in temperature.

Specific heat refers to the amount of energy required to raise the temperature of unit mass by one unit of temperature.

Specific heat capacity of aluminium is, $c_{Al}=0.9\text{J/g}\cdot \text{°C}$

Specific heat capacity of lead, $c_{Pb}=0.16\text{J/g}\cdot \text{°C}$

As the specific heat capacity of aluminum is higher than that of lead, aluminum will melt more ice than lead.
