Jordan wants to know if the mass of his hot cheetos will change at high temperatures. He finds that his hot cheetos have a mass of 300 grams. When he melts his hot cheetos into liquid, will the mass increase, decrease, or stay the same?
The mass will stay the same.
Jordan heats up his hot cheetos so much that they turn into gas. Will the mass increase, decrease, or stay the same?
The mass will stay the same.
Why will Jordan's hot cheetos stay the same mass even when the temperature increases?
The particles stayed the same when the temperature increased. They just had more energy so they moved around faster.

Ms. Jablonsky adds baking soda to vinegar in a closed container with a balloon on top. When they mix, a chemical reaction takes place and the balloon inflates. Why did the mass stay the same even though the volume increased?
The mass stayed the same because no particles left the container. The particles in the new gas had more energy so they were more spaced out.
