How could you changed the mass of an object?
What is by taking matter away from the object? (Example: Say a person weighed 200 pounds, over time they lost 10 pounds and now weigh 190. They lost matter and now their overall mass is smaller.)

What can you tell about matter by how its particles move?
What is whether it is a solid (particles are packed tightly together), liquid (particles are close together, but have room to move around), or gas (particles move freely all over)?
