100
Solid, liquid, gas, and plasma are referred to as this.
What is states of matter?
100
The force that acts on the surface of a liquid.
What is surface tension?
100
This describes the speed of gas particles.
What is fast and free-moving?
100
A substance changing from a solid, to liquid, to gas would be described as this.
What is a change in state?
100
This explains the difference between boiling and evaporation.
What is evaporation occurs at the surface of a liquid and boiling occurs throughout the liquid?
200
Particles of matter that are not able to overcome the force of attraction between them.
What is a solid?
200
A liquid's resistance to flowing.
What is viscosity?
200
This term is used to describe how fast the particles in an object are moving.
What is temperature?
200
This is why the metal gallium would not make good jewelry.
What is gallium's melting point is lower than our body temperature?
200
This is why water boils at a lower temperature at higher elevations.
What is the atmospheric pressure is lower at higher elevations so the vapor pressure doesn't have to be as high to equal the atmospheric pressure?
300
The particles of this substance move fast enough to overcome nearly all the attraction between them.
What is a gas?
300
This compares the surface tension and viscosity of vinegar and vegetable oil.
What is vinegar has a lower surface tension and lower viscosity than veg. oil?
300
The amount of force exerted on a given area of surface.
What is pressure?
300
If energy (heat) is absorbed (gained) it is considered this type of change.
What is an endothermic change?
300
This must happen for a gas to become a liquid.
What is energy must be removed?
400
Has no definite shape, but has a definite volume.
What is a liquid?
400
This determines the viscosity of different liquids.
What is the strength of attraction between the particles of liquid?
400
A filled balloon that pops in the hot sun can be explained using this law. What does the law say?
What is Charles's law?
400
A liquid turning to a solid would be this kind of change.
What is an exothermic change?
400
This is why the film caps popped off in our lab when dry ice was enclosed inside.
What is the pressure from the gas built up until the cap couldn't hold it in any longer?
500
This would name and describe the two types of solids.
What is a crystalline solid (particles are in repeating patterns and rows) and amorphous solid (particles have no special arrangement).
500
This explains the difference in boiling point of 5mL of water and 5 L of water.
What is the boiling points are the same regardless of the amount of water?
500
An air bubble increasing in size as it reaches the surface of water can be explained using this law. Explain why?
What is Boyle's law?
500
A liquid reaches its boiling point under these conditions.
What is when the vapor pressure inside the bubbles equals the atmospheric pressure?
500
Sublimation of dry ice is considered to be this type of change.
What is an endothermic change?
