Gas *cont*
Change of State
100
has a definite shape and a definite volume.
What is a solid
100
Has a definitie volume, but no shape of its own.
What is a liquid
100
Has neither a definite volume or definite shape
What is a gas
100
When temperature is CONSTANT, this is the relationship between Pressure and Volume.
What is as pressure increases, volume increases, if pressure decreases, volume decreases.
100
Melting
What is changing from a solid to a liquid
200
This forms when particles of a solid have a repeating pattern.
What is a cystalline solid
200
Particles of a liquid
What is are packed closely and move around freely
200
Particles of a gas
What is move freely and fill all space avaliable
200
Charles's Law
What is states that when a temperature of a gas at CONSTANT pressure is increased, its volume increases.
200
The two items to Scientists use to identify a substance
What is Melting Point and Boiling Point
300
This type of solid forms when particles are not arranged in a certain pattern. They get softer and softer.
What is an amorphous solid
300
Surface Tension
What is an inward force or pull among the molecules of a liquid that brings the molecules on the surface together.
300
Pressure
What is the force of the outward push divied by the area of the walls of the container
300
When VOLUME is constant, this is the relationship between temperature and pressure.
What is as temperature increases, so does pressure. As temperature decreases, so does pressure.
300
Difference between Vaporization and Condensation
What is Vaporization is the change from liquid to gas, Condensation is the change from gas to liquid.
400
Solid has what kind of thermal energy
What is the lowest amount of thermal energy
400
Viscosity and an example of low and high
What is the resitance to flowing. High viscosity is honey, low is water or vinegar.
400
What pressure is measured in
What is Pa (Pascals) or N/m2
400
When the produce of two variables is constant.
What is inversely proportional
400
The Difference between the two types of vaporization
What is Evaporation occures only on the surface of a liquid, Boiling occurs both below the surface and at the surface of a liquid.
500
The particles of a solid
What is closely packed together and in fixed positions
500
The Thermal Energy in a Liquid
What is liquid has less thermal energy than a gas and more than a solid.
500
The three items that must be taken into account for a gas
What is Pressure, Volume, Temperature
500
Law that is inversely proportional
What is Boyles's Law
500
During the winter, if the snow on the ground is still melting and it is freezing outside. Explain Why.
What is Sublimation, it is where solids gain enough energy to form a gas.
