States of Matter
These are the 4 states of matter.
What are solid, liquid, gas, and plasma.
This is the definition for the word 'phase change'.
What is when a substance changes from one state of matter to another.
This means that energy is released or exits a substance.
What is exothermic.
This is what is constantly in motion.
What is matter (particles or atoms).
These are the behaviors of particles like for a solid, liquid, and gas?
What are solid particles move slow, are orderly, and compact.
What are liquid particles have an average speed, are random, and spread a little apart.
What are gas particles move very fast, are random, and spread very far apart.
This phase change goes from a liquid to a gas.
What is vaporization.
Bonus: What are the 2 types of vaporization and how do they differ?
This means energy is absorbed or comes into a substance.
What is endothermic.
Matter makes up this.
What is everything.
Describe what plasma is and at what temperature it is found.
What is when particles are at extremely high temperatures, found in space, particles are more spaced out and random than a gas.
Bonus: Give an example of plasma.
This phase change occurs when a solid turns into a gas.
What is sublimation.
Bonus: Give an example of sublimation.
When condensation occurs energy is this.
What is energy is released.
Bonus: Is this endothermic or exothermic?
This is what 'kinetic' means.
What is moving.
Rank the densities of the states of matter from smallest to largest.
What is gas, liquid, solid.
This is the definition for the heat of fusion.
What is the temperature that something melts.
Bonus: Define heat of vaporization.
Identify all of the phase changes that are endothermic.
What are melting, vaporization, and sublimation.
When a substance gets warmer and particles expand this is called what.
What is thermal expansion.
Describe the difference between density and buoyancy.
Density describes how compact particles are and buoyancy is the force on an object when in a substance that allows the object to float. (buoyancy = weight of object)
State each phase change and an example of each.
What are freezing (frozen pond), melting (candle when lit), vaporization (boiling: water on the stove) (evaporation: puddle in the sun), condensation (steam on mirror), sublimation (solid air freshener), and deposition (frost on car window)
Identify all of the phase changes that are exothermic.
What are freezing, condensation, and deposition.
Bonus: What is deposition?
This happens when particles move further apart.
What is they move faster and are more random.
