What are the three common states of matter?
Solid, Liquid, and Gas
What property measures how much matter is in an object?
Mass
Which two states of matter can change shape but keep the same volume?
Liquids and solids
What is the process called when a solid turns into a liquid?
Melting
Is air matter? Why or why not?
Yes, because it has mass and takes up space
Which state of matter has a definite shape and volume?
Solid
What property tells us how much space an object takes up?
Volume
How is a liquid different from a gas in terms of particle arrangement?
Liquid particles are closer together; gas particles are far apart
What do we call the process when a liquid turns into a gas?
Evaporation
Name a liquid and a gas you might find in your kitchen.
Liquid - water; Gas - steam or air
What happens to the particles in a gas compared to those in a solid?
Gas particles move faster and are farther apart than solid particles
If you heat an object, which property of matter might change?
Temperature
Why can gases be compressed but solids cannot?
Gas particles have space between them and can be pushed closer; solid particles are tightly packed
What happens to the particles during freezing?
Particles slow down and move closer to form a solid
How can you tell if something is matter?
If it has mass and takes up space
What state of matter has particles that move freely but stay close together?
Liquid
What property of matter can be observed without changing the substance?
Physical property (such as color, texture, or shape)
Which state of matter flows and has particles that can slide past each other easily?
Liquids
What is condensation?
When a gas changes into a liquid
Give an example of matter changing state in your daily life.
Ice melting to water or water boiling to steam
How does plasma differ from the three common states of matter?
Plasma is an ionized gas with charged particles and is found in stars and lightning
How can you measure the volume of an irregularly shaped object?
By water displacement method
Explain why solids keep their shape but liquids take the shape of their container.
Solid particles are tightly packed in fixed positions; liquid particles are close but can move past each other
Describe what happens at the particle level during sublimation.
articles change from solid directly to gas without becoming liquid
Explain why sound cannot travel through a vacuum in terms of matter.
Sound needs particles to travel through, and a vacuum has no matter (no particles)
