Evaporating dish facts for kids

An evaporating dish is a special bowl used in science labs. It helps scientists turn liquids into a gas. This process is called evaporation. These dishes are usually made from strong materials like ceramics.

What is an Evaporating Dish?

An evaporating dish looks like a shallow bowl. Scientists use it to heat liquids. When a liquid gets hot enough, it changes into a gas. This leaves behind any solid stuff that was dissolved in the liquid. Imagine boiling water until it all disappears. If there was salt in the water, the salt would be left behind in the dish.

How Does Evaporation Work?

Evaporation happens when liquid molecules gain enough energy. They then escape into the air as a gas. Heating the liquid in an evaporating dish speeds up this process. The wide, shallow shape of the dish helps too. It gives the liquid a large surface area. This means more liquid can turn into gas at once.

What are Evaporating Dishes Made Of?

Most evaporating dishes are made from ceramics or porcelain. These materials are very strong. They can handle high temperatures without breaking. This is important because the dishes are often heated over a Bunsen burner or on a hot plate. Porcelain is a type of ceramic. It is known for being very durable and resistant to chemicals.

Where are Evaporating Dishes Used?

Evaporating dishes are common tools in many science labs. They are used in chemistry classes at school. Scientists also use them in research labs. They help to separate mixtures. For example, they can be used to get salt from saltwater. They are also useful for making crystals. This happens when a dissolved solid is left behind after the liquid evaporates.
