Changes of state
Marco put a pot of water on to boil eggs. After a few minutes, all the water was gone.
What is vaporization
Added or removed to create a change in state of matter
What is thermal energy
What is particles heat up and the pressure increases and pushes on the sides of the balloon making it drift upward.
The amount of force exerted on a balloon by the gas in the balloon.
What is pressure
A change of state that involves adding energy to a substance
What is melting
During a shower, the mirror is cooler than the air around it and turns vapor to water.
What is condensation
Increases as temperature is added and molecules move faster.
What is kinetic energy
Describes particles and their interactions in all states of matter
What is the kinetic molecular theory
The measure of the average kinetic energy of the particles of a substance.
What is temperature
The measure of a fluid's resistance to flow
What is viscosity
Attractive forces between particles pull them close together so that they keep their position
What is a solid
Thermal energy is added to a cup of water and causes the particles to _____________ and _______________.
What is move faster and get farther apart
When particles in matter collide, no energy is lost
Particles are always in constant random motion
Small particles make up all matter
What is the kinetic molecular theory
When the space in the container gets smaller, the ________ decreases.
What is volume
The surface particles of matter experience a strong downward pull and stretch tight enough for a spider to walk on it.
What is surface tension
Dry ice is a solid that changes directly to a gas when thermal energy is added.
What is sublimation
Attractive forces are not as strong in this form of matter and particles slide past each other.
What is liquid
Which factor is the measure of all the potential and kinetic energy in a substance? (hint it is the type of energy that involves temperature.)
What is thermal energy
The law that states a direct relationship between pressure and temperature.
What is Charles Law
The state of matter with the most kinetic energy and the least potential energy.
What is Gas
Snow forms in clouds because vapor turns directly into ice.
What is deposition
Lightning flashes contain this state of matter
What is plasma
The gaseous state of a substance that is normally a solid and a liquid at room temperature.
What is water vapor
Describes the relationship between volume and pressure.
What is Boyles law
A liquid that resists flow and is hard to pour
What is high viscosity
