What are particles
Anything that has mass and takes up space is called what?
What is matter?

What kind of gas stays in the atmosphere in consistent amounts?
What is a permanent gas?
Name the three states of matter
What is solid, liquid, and gas
What happens to air particles when a gas is compressed?
What is they move closer together and bump into each other more often?
This middle layer is above the stratosphere and gets very cold.
What is the mesosphere?
What kind of gas changes its amount based on the environment
What is a variable gas?
What does it mean when a gas expands?
What is it that fills more space and the particles spread out?
True or False: The particles themselves get smaller when compressed.
What is False

What is the force between Earth and an object’s mass called?
What is weight?
This measurement tells us how much matter is in an object or substance like air.
What is mass
This is the final layer, marking the edge of space.
What is the exosphere?
What is the difference between weight and mass?
What is mass is the amount of matter, and weight is the force of gravity acting on that matter?
How can you prove air has mass?
What is by weighing it or using a balance to compare?
