Conditions of Use
Heat and Matter
I learned what is matter, matter is anything that takes up space. I also learned what expand means to take up more space and it expands. I also learned what contraction is, it is to take up less space or to suck in. I like the popcorn lad, and I don't like to do the study guides to do.
