States of Matter
This state of matter has a fixed shape and fixed volume.
What is a solid?
This process turns a solid into a liquid.
What is melting?
When volume decreases, this increases.
What is pressure?
This tiny particle is the building block of matter.
What is an atom?
Increasing temperature increases this type of particle energy.
What is kinetic energy?
This state has a fixed volume but takes the shape of its container.
What is a liquid?
During this phase change, temperature remains constant while particles gain energy and move apart.
What is boiling?
This law states that pressure and volume are inversely proportional.
What is Boyle’s Law?
A group of atoms bonded together that act as a unit.
What is a molecule?
Metals are shiny and malleable because their atoms are arranged in these extended structures.
What are metallic bonds / extended atomic structures?
This state has no fixed shape and no fixed volume.
What is a gas?
This process happens only at the surface of a liquid.
What is evaporation?
This device measures gas pressure.
What is a pressure gauge?
This type of bond forms when electrons are shared.
What is a covalent bond?
Nonmetal gases boil at low temperatures because they have this weak attraction between particles.
What is low attraction between particles?
This theory says all matter is made of particles that are always moving.
What is the Particle Theory?
This law states that volume increases as temperature increases (if pressure is constant).
What is Charles’s Law?
At high altitudes, boiling occurs at a lower temperature because this is lower.
What is air pressure?
This type of compound conducts electricity when dissolved in water.
What is an ionic compound?
During freezing, this must be removed from a substance.
What is thermal energy?
This is the energy an object has due to its movement.
What is kinetic energy?
This type of energy depends on mass, temperature, and material.
What is thermal energy?
Adding more particles to a sealed container will cause this to increase.
What is pressure?
This phrase explains why sugar dissolves in water but oil does not.
What is “like dissolves like”?
Explain why a bathtub of water at 20°C has more thermal energy than a cup of coffee at 20°C.
What is because thermal energy depends on mass, and the bathtub has more particles?
