Part. Theory / Visc.

Terms on viscosity and particle theory.

QuestionAnswer
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
The amount of a substance dissolved in a specific volume concentration
When you increase the concentration of a substance, its viscosity (increases or decreases) 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 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
The three-word phrase that describes the change from any state of matter to another change of state
