states of matter Flashcards
Are solids fixed together?
Yes, the particles in solids are fixed together ( stuck together)
Liquids have ______ points
Boiling points
Solids have ______ points
Melting points
Solids also have what points (besides the melting point)
Freezing points
Melting points and freezing points will always be what?
The same temp
Crystalline is in what state of matter
Solid - particles are orderly repeating
What is an allotrope?
An allotrope is a form of an element that has a different molecular structure from another form of the same element. For example, carbon has several allotropes, including diamond, graphite, and fullerenes, each with distinct properties due to their different molecular arrangements.
Kinetics means _____
Motion
How is kinetic theory different from kinetic energy?
3 assumptions of kinetic theory does not include motion
What do you call empty space with no particles and pressure?
Vaccum
Increase in atmosphere, what happens to the pressure
Pressure decreases
How is kinetic energy related to potential energy?
Kinetic energy is stored energy in potential energy
Kelvin (K)
Is a type of measurement to measure temperature.
If particles in gasses have kinetic energy then …?
so will liquids
What is evaporation
The conversion of liquid to gas at the surface. (Needs to happen on a body of water at the SURFACE)
What kind of molecules are needed to evaporate?
As the molecules escape, they leave behind the lower temperature molecules. Lower average kinetic energy
What is vapor pressure?
Vapor pressure is the force exerted by a gas above a liquid.
A balance is met after the vapor pressure, and what happens after?
Condensation
Vapor pressure data represents what?
How volatile the substance is
How is boling point and vapor pressure related?
The boiling point is the temperature when the vapor pressure will equal atmosphere pressure.
