Chemistry Flashcards
which state of matter has the most kinetic energy
gas
which state of matter has the least kinetic energy
solids
what is it called when a solid turns into a gas
sublimation
what is it called when a gas turns into a solid
deposition
what is it called when a gas turns to liquid
condensation
what is it called when a liquid turns to a gas
evaporation
what is it called when a solid turns to liquid
melting
what is it called when a liquid turns to lsolid
freezing
what does evaporate mean
a liquid becomes a gas at any temperature.
what does freezing/solidifcation mean
liquid to solid at a fixed temp
what does melting mean
a solid to liquid
what does condensation mean
a gas to a liquid
what does boiling mean
liquid becomes a gas at a fixed temperature
why does ammonia gas travel fatser than hydrochloride gas
this is because hydrochloride gas is heavier than ammonia
what is the unit for ammonia
NH cubed
what is the unit for hydrogenchloride
HCC
which state of matter allows particles to slide over each other?
liquid
what is the difference between boiling and evaporating
boiling is at a fixed temp and evaporating can be at any temp
what does diffusion mean
The net (overall) movement of particles from a
HIGH to LOW concentration.
what does solvent mean
liquid that dissolves things
what does solute mean
a solid that dissolves
what does solution mean
when a solute is dissolved in a solvent
what does Saturated solution mean
when no more solute will dissolve
what does soluble mean
when a solute dissolves
what does insoluble mean
solute cant dissolve
what is a solubilitiy curve
a graph of solubility, measured in g/100 g water, against temperature in °C.
is sand insouluble or soluble
insoluble
