# How Much Does a Cubic Foot of Water Weigh?

When the water is 70 degrees Fahrenheit, a cubic foot of water weighs about 62.3 pounds. But when the temperature changes, so does the weight. This is because the waterâ€™s density depends on its temperature, and the weight depends on the waterâ€™s density. Since cooler water is denser than warmer water, a cubic foot of water that is less than 70 F weighs more. If the water is warmer than 62.3 pounds per cubic foot, it weighs less.

The USGS Water Science School says that a gallon of water at 70 degrees Fahrenheit weighs about 8.33 pounds. Start by multiplying the weight of a gallon of water by 7.48, which is how many gallons are in a cubic foot. The result is the weight of one cubic foot of water.

## Does a foot cubed of ice weigh more than a foot cubed of water?

Ice doesnâ€™t follow the temperature rule because when water freezes, its molecules spread out, making the ice bigger and less dense. Ice floats on water because of this. In comparison, a cubic foot of water at 70 degrees Fahrenheit weighs 62.3 pounds, while a cubic foot of ice weighs 57.2 pounds. So, a cube foot of ice weighs more than five pounds less than a cube foot of water.

## How water floats

The Archimedes Principle says that an objectâ€™s level of buoyancy is based on both its weight and the amount of water that its weight moves. For example, an ocean liner floats because it takes up a lot of water.

Due to the minerals that are dissolved in it, a cubic foot of saltwater weighs a little bit more than a cubic foot of freshwater. This means that an object that weighs a little more per cubic foot than fresh water will sink, while the same object that weighs a little less per cubic foot than salt water will float.

Divers can change how much air they have in their tanks to change how much they float. This lets them float, sink deeper, or stay in the same place, which is called neutral buoyancy.

## Why is water important?

We use water in farming, in manufacturing, as a source of energy, for recreation, and most importantly, for our health.

Itâ€™s important to stay hydrated by eating and drinking the right things. Water helps you control your body temperature, quenches your thirst, keeps your tissues moist, lubricates your joints, and protects your spine.

Water also keeps you from getting dehydrated when itâ€™s hot, when youâ€™re working out, or when youâ€™re sick. How much water you need to stay healthy depends on how active you are, whether or not you are sick, and the weather. As a general rule, if you drink water when youâ€™re thirsty and feel better, that should be enough water for your body.

## Types of bodies of water

There are big and small bodies of water, as well as saltwater and freshwater, among the different kinds of water bodies.

The oceans are the largest bodies of water. The Pacific Ocean is the biggest of these, followed by the Atlantic, Indian, Southern, and Arctic oceans. Some parts of oceans, like the Bering Sea and the Mediterranean Sea, are called seas. There are also straits, bays, and gulfs that are parts of oceans.

Lakes, like the Great Lakes of North America, are bodies of water that are completely surrounded by land. Rivers and streams are bodies of water that flow over the ground. The Yangtze River, the Nile River, and the Amazon River are all well-known rivers.

A glacier is a body of water that has frozen over. About 10% of the land is covered by ice from glaciers. Surprisingly, about three-quarters of the freshwater on Earth is in this glacial ice.

## Well-known Water Bodies

Between the icy peaks of Taylor Glacier, where Blood Falls is, there is a pool of liquid that looks like blood. This is iron-rich water that leaked out of a very salty lake under the glacier. The iron reacts with the oxygen in the air, which turns it into a blood-red waterfall.

As you might guess, Boiling Lake is a lake that boils. Under the lake, molten lava flows, heating the water and pushing hot gas and steam through it. If youâ€™re hiking in Morne Trois Pitons National Park and come across a bubbling lake, itâ€™s best not to jump in.

In Indonesia, there are three crater lakes on the top of the Kelimutu volcano. These lakes are called the Kelimutu Crater Lakes. Even though they are next to each other, they are each a different colour that sometimes changes. These colours are as different from one another as black and white, red and green, and chocolate brown and blue.
