Chapter U5.3, Problem 11E

Interpretation Introduction

Interpretation: The possibility of a situation in which an ice cube actually heats up something else needs to be explained.

Concept Introduction: There are three simple ways to transfer heat. They are- convection, conduction and radiation. These three processes explain heat transfer from one object to another. For fluids, heat is mostly transferred by convection. Another way of transmitting heat is through conduction. The third way to heat transfers is radiation.

Answer to Problem 11E

Conduction does not require any movement of a material, but rather a transfer of energy within a material (or between in contact substances). Heat transfers to the ice cube through conduction. When enough energy is transferred into the ice cube then it is melt.

Explanation of Solution

The sensation of hot or cold depends on the direction of heat transfer. For example, if you hold an ice cube, your hand will feel cold as heat transfers from your hand from the ice cube.

Conclusion

Ice cube melts as heat transfers to the ice cube through conduction.
