Question | Answer |
Anything that flows is called a | fluid |
This state has a definite shape and volume | solid |
This state has a definite volume, but not a certain shape | liquid |
This state's volume and shape are determined by its container | gas |
All matter is made of tiny | particles |
All particles in a pure substance are the | same |
What is between particles | space |
Particles are always | moving |
As particles gain energy, they go | faster |
As particles lose energy, they go | slower |
Particles in a substance are ______ to one another | attracted |
When the physical state of a substance is transformed to another, it is called a change of | state |
Going from a solid to liquid is called | melting |
Going from a liquid to a gas is called | evaporation |
Going from a gas to a liquid is called | condensation |
Going from a liquid to a solid is called | solidification |
Going from a solid to a gas is called | sublimation |
Going from a gas to a solid is called | deposition |
Rapid vaporization is called | boiling |
The temperature at which a substance goes from a liquid to a solid is called its ________ point | freezing |
The temperature at which a substance goes from a solid to a liquid is called its ________ point | melting |
Resistance to flow is also called | viscosity |
The time it takes a fluid to flow from one point to another is called its | flow rate |
The energy of motion is called _________ energy | kinetic |
The viscosity of a liquid (increases or decreases) when the temperature goes up | decreases |
The viscosity of a liquid (increases or decreases) when the temperature goes down | increases |
When particle size increases, viscosity (increases or decreases) | increases |
Anything that takes up space and has mass | matter |
This is a measure of the average kinetic energy of something's particles | temperature |
The three-word phrase that describes the change from any state of matter to another | change of state |
the two-word term that means the volume of something increases when the temperature increases | thermal expansion |
the two-word term that describes how the volume of something shrinks when it cools | thermal contraction |
this is a graph or plot of temperature vs time | heating curve |
