A marble takes up a small volume while a star occupies a large volume. Words such as big, little, long, or short are used to describe volumes. What is volume? Volume is the amount of space something occupies. Mass is a measure of the matter in an object while weight is a measure of gravity’s pull on an object. You should also know there is a difference between mass and weight. You might have a large object with very little mass such as a balloon filled with helium (He). You might have a small object with a lot of mass such as a statue made of lead (Pb). What is mass? Mass is the amount of matter in an object. Matter is defined as anything that has mass and takes up space (it has volume). Those atoms go on to build the things you see and touch every day. Atoms and compounds are all made of very small parts of matter. If all of those short statements are true, then I have to apply logic to come up with more complicated answers.What is matter? Matter is everything around you. "Jim uses power tools" would eliminate certain occupations, while "Joe works at night" would point me towards others. I might have to figure out the occupations of four people based on the conflicting or incomplete pieces of information provided in the puzzle. I sometimes work logic puzzles I find in gaming magazines, and they usually start off with atomic sentences. A really long compound complex sentence could be read as positives and negatives: "Jim hates olives, but Jan likes Italian food, so the chef makes a salad but the waiter removes the olives." It's all about the relationship between all of those atomic sentences. It does make sense to think of them as building blocks, however. I remember dealing with these kinds of short sentences in a class on logic, but I didn't know they were called atomic sentences.
