A liquid is a fluid that takes the shape of the container it is in. The shape is not definite, but rather depends on the shape of the container it is held in. When a solid is heated above its melting point, it becomes a liquid. The highest temperature that a liquid can exist at is called its critical temperature. Some examples of liquids include water, soap, detergent, paint, nail polish, and many others.

One question that I have is: When does a liquid become a gas?
