Chapter 17, Problem 86A

Interpretation Introduction

Interpretation: Thermochemical principle due to which our fingers quickly begin to feel cold when we touch an ice cube needs to be illustrated.

Concept Introduction: The process in which the molecules are moved from a high temperature to a low temperature is known as Heat transfer.

Answer to Problem 86A

Thermochemical principle due to which our fingers quickly begin to feel cold when we touch an ice cube is Heat transfer.

Explanation of Solution

Given Information: Our fingers quickly begin to feel cold when we touch an ice cube.

When two objects have different temperatures, a transfer of heat takes place from the warmer object to the colder one. When we touch an ice cube, our fingers quickly begin to feel cold as it is losing heat energy due to heat transfer from our warm hand to the cold ice which melts it.
