Short Answer

Give an example of a physical property that varies with temperature and describe how it is used to measure temperature?

Volume is an example of a physical property, which varies with temperature. For more substances, volume increases with temperature. This is the basis for thermometers, and thermometers make use of measurable physical property that varies with temperature.

Step by Step Solution

Step 1: Concept Introduction

The concept of temperature is derived from the common concept of hot and cold. When an object receives heat its temperature began to rise, and its physical properties can be changed.

Step 2: Volume and thermometer

A property that changes with temperature is known as thermometric property. These include pressure, volume, electrical resistance, etc. Any physical properties which consistently and measurably on temperature can be used as the basis of a thermometer. One such is volume. For most substances volume increases with temperature.

In a common type of thermometer, the alcohol expands very fast than the glass. When the thermometer’s temperature increases, the liquid from the bulb expands by producing a large change in the length of the column for a small variation in the temperature.
