Changes

Hot or cold and heavy or light are '''not properties'''. They can describe something, but they are not properties. Ask yourself; Can I change it? If the answer is yes, then it is not a property of the material. For example; a brick is rough, hard, redish brown, not see through, dull, firm , stiff and a little bit absorbent. If I cut a brick in half it is still all of those things, but now it is not as heavy. So heavy and light are not properties. If I put a cold brick in an oven it still has all the same properties, but now it is hot. So hot and cold are not properties of a material.
