compress

Compress means to squeeze or press something together so that it takes up less space. In science, the word compress is often used to describe the process of reducing the volume of a substance.

When a substance is compressed, the molecules of the substance are forced closer together. This makes the substance denser and harder.

Compressing a substance can be done in a number of ways. For example, we can compress a gas by putting it in a container and reducing the volume of the container. We can also compress a liquid by putting it in a container and applying pressure to the container.

Compressing a substance can have a number of effects. For example, it can increase the temperature of the substance, and it can change the physical properties of the substance.

Imagine that you are a ball of dough. If you squeeze the dough, it will become smaller. This is because the molecules of the dough are being forced closer together. In the same way, when we compress a substance, we are forcing the molecules of the substance closer together. This makes the substance smaller and denser.
