How can you turn something solid into a liquid?
Liquids are everywhere around us. We drink them, cook with them, and use them to clean our homes. But what exactly is a liquid, and how can you make one? A liquid is a substance that flows easily and takes the shape of its container. It is made up of tiny particles that are close together but not as close as they are in a solid. These particles are constantly moving and colliding with each other, which gives liquids their fluid properties.
There are many different ways to make a liquid. One way is to melt a solid. When a solid is heated, its particles gain energy and start to move more quickly. This causes the solid to expand and become less dense. Eventually, the particles will move so quickly that they break free from the solid structure and the substance will become a liquid.
Another way to make a liquid is to dissolve a gas in a liquid. When a gas is dissolved in a liquid, the gas molecules mix with the liquid molecules and form a new substance. The new substance is a liquid because the gas molecules are now surrounded by liquid molecules and cannot escape.
Liquids are important for many reasons. They are essential for life, as they make up the majority of our bodies. Liquids are also used in many industrial processes, such as manufacturing, food processing, and transportation.

- Henry's Law: Henry's Law states that the solubility of a gas in a liquid is directly proportional to the partial pressure of the gas above the liquid. This means that the more gas that is present above the liquid, the more of the gas will dissolve in the liquid.
- Applications: Dissolving is used in a wide variety of applications, including:
- The production of carbonated beverages
- The production of flavored drinks
- The production of pharmaceuticals
- The removal of impurities from liquids
- The separation of gases from liquids
