Electrons have a negative charge. The proton moves around the nucleus of an atom, which is in the center. The charge of an electron is opposite but equal to the charge of a proton. Atoms have the same number of electrons as protons. We cannot see these with our eyes, and even with a high-powered microscope, they are too tiny and too low in mass to see.

Atomic theory is the name of the theory described in the question. Atoms are very tiny and cannot be seen without a microscope. They are made up of parts that determine what the atom is, how it acts, and its mass. Inside of atoms are protons, neutrons, and electrons.

Matter is anything that takes up space. Matter is in the form of solid, liquid, or gas. Solids, liquids, and gases are made of tiny particles called atoms and molecules. In a solid, the particles are very attracted to each other. They are close together and vibrate in position but don’t move past one another. In a liquid, the particles are attracted to each other but not as much as they are in a solid. The particles of a liquid are close together, always moving, and can slide past one another. In a gas, the particles have very little attraction to each other. They are very far apart compared to the particles in a solid or liquid and are constantly moving. The particles don’t interact with one another but just hit and bounce off of each other when they collide.

The answer is 15 grams because 10+5 = 15 and the amount of grams should stay the same since matter is conserved.

The Law of Conservation of Matter says that the amount of matter stays the same, even when matter changes form. Sometimes it may seem that matter disappears during a science experiment, but this law tells us that matter cannot magically appear or disappear, it simply changes from one form to another.

The answer is the graph where the mass does not change.

Mass is the measurement of how much matter is in an object. The Law of Conservation of Matter says that matter stays the same, even when matter changes form. Sometimes it may seem that matter disappears during a science experiment, but this law tells us that matter cannot magically appear or disappear; it merely changes from one form to another. This means that the mass does not change. If I find the mass of a whole cookie and then break it up and put all of the pieces back on the scale, the mass will be the same because the matter has been conserved.

During this demonstration, Meredith's teacher collects data regarding the mass of the ice cubes, the water, and then the two when combined and melted. She does provide evidence that matter is conserved. The Law of Conservation of Matter says that matter stays the same, even when matter changes form. Sometimes it may seem that matter disappears during a science experiment, but this law tells us that matter cannot magically appear or disappear; it merely changes from one form to another. The ice cubes and water had a mass of 98.3 grams when combined, and the mass stayed the same when the ice cubes melted. This showed no loss in mass or change in matter when the cubes went from a solid to a liquid.
