All substances are made of matter. Matter is anything that has mass, or weight, and takes up space. Solids have their own shape and take up a certain amount of space. Liquids take up a certain amount of space too, but they take the shape of the container they are in. Gases will completely fill any closed container (take the shape of its container) and assume the amount of space in the container. (e.g., Helium gas put into a balloon takes the shape of the balloon because the balloon defines its shape.) My chair is a solid, the juice in my cup is a liquid and the air I am breathing in and out is a gas. 1. Click to add response. 2. Watch the short video about ice on slide two. 3.
