A fluid, or a liquid, is difficult to explain but scientifically, it is a substance that has had its molecules spread out through the transfer of thermal energy so that they no longer maintain a permanent shape.

In other words, when a substance is heated, its molecules move faster and spread out so that the substance will now form to a non-definite shape.
