When this occurs, matter keeps the same chemical properties.
What is a physical change
100
solid to liquid
What is melting
100
This phase's particles are close together, vibrate, move about, slide past each other, and are close together with no regular arrangement.
What is a liquid
100
A substance that has a fixed volume but no fixed shape. (solid, liquid, gas, or plasma?)
What is liquid
100
Phases changes are physical (P) or chemical (C)?
What is physical
200
When one kind of matter changes into a different kind of matter with different properties.
What is chemical change
200
liquid to solid
What is freezing
200
The particles of this phase vibrate rapidly, move freely at high speeds, and have no regular arrangement.
What is a gas
200
particles are very far apart; indefinite shape and volume (solid, liquid, gas, or plasma?)
What is gas
200
During a phase change, the temperature does OR does not change?
What is does not change? Changes before and after this point.
300
mass divided by volume equals
What is density
300
liquid to gas
What is vaporization
300
The particles of this phase are tightly positioned, vibrate very little, generally do not move from place to place, and have a regular, consistent pattern.
What is a solid
300
particles have the highest energy content of all the phases and actually split apart (solid, liquid, gas or plasma?)
What is plasma
300
Given Mass = 25 g and Volume= 5 cm3. What is the density?
What is 5 g/cm3
400
energy is required to make what happen
What is phase change or physical change
400
gas to liquid
What is condensation
400
As the kinetic energy of the particles of a solid increase, they begin to accelerate and bounce off each other more frequently, causing the stability of the solid to weaken and so a liquid is formed. This is called...
What is melting or melting point
400
two phases that have definite volume
What is solid and liquid
400
Density = 15 g/mL Mass= 3 g What is the volume?
What is .2 mL
500
this shows how a substance changes with temperature over time
What is phase change diagram or curve
500
solid to gas
What is sublimation
500
As the kinetic energy of the particles of a liquid increase, they begin to accelerate and bounce off each other more frequently, causing the stability of the solid to weaken and so a gas is formed. The _____has been reached.
What is boiling point
500
state of matter in which will spread to fill entire space or volume
What is gas
500
Given 4 liquids in a graduated cylinder. Their densities are 3.25, 1.00, 2.45, and .65. Which liquid will be on the bottom and which will be on the top?
