The weight of water is not constant due to fluctuations in temperature. Cold water is denser than warm water, thus the heaviest.

When weighed in a container like a gallon, the density of the water changes with the thermal fluctuations. The good news is the variations in weight are minimal.

## What is a Gallon?

The gallon is an Imperial system and U.S. customary unit of measurement for volume. It is equivalent to 4 quarts or 3.785 liters.

## What is the Weight of One Gallon of Water?

## What Can Change the Weight of Water?

Temperature fluctuations affect the behavior and weight of water. Atmospheric changes have a great impact on the mass of water as well.

## How Can Temperature Affect the Weight of Water?

When you heat water, you increase its energy. This results in a decrease in density, i.e., water molecules become more spaced out.

Therefore, if you had water in a container, it would weigh more weigh cold. Heat it, and it will weigh less.

Hot water weighs less and cold water weighs more. When the temperature of the water approaches freezing, it gets lighter.
