Does Water Temperature Cause Metal to Expand and Contract


Published on Sep 05, 2023

Abstract

The objective: Discover how water temperature affects metal.

Research Questions:

Does metal change in response to temperature?

What happens when a metal contracts or expands?

All matter tends to change shape and volume in response to changes in temperature, a process called thermal expansion. In this experiment, we'll observe the effects of thermal expansion on metal, which is an excellent conductor for heat.

Materials:

Two identical containers with tight-fitting metal vacuum lids, such as pickle jars

Hot and cold running water

Protective gloves

Stop watch

Does Water Temperature Cause Metal to Expand and Contract

Experimental Procedure

1. Run cold water over one container, right side up, for 30 minutes. Then try to open it. Time how long it takes to open.

2. Now run hot water over the second container for 30 minutes. Time how long it takes to open.

3. Record your results.
