100
name the 3 states of matter
solid, liquid, gas
200
the state of matter in which the volume and shape of a substance are fixed
solid
200
the law that states the volume of a gas is directly proportional to the temperature of a gas when pressure is constant.
Charles law
200
the change of state from a solid to a liquid
melting
200
what is it called when energy is gained by the substance as it changes state.
endothermic
200
what is a liquids resistance to flow.
viscosity
300
the resistance of a gas or liquid to flow
viscosity
300
who came up with the law that a fixed amount of gas at a constant temperature, the volume of the gas is inversely related to pressure
Robert Boyle's
300
the change of state from a gas to a liquid
condensation
300
what is it called when energy is removed from the substance as it changes state.
exothermic
300
liquids change ______ but not ______
shape, volume
400
a measure of the size of a body or region in a 3D space
volume
400
for Charles law what happens if the temperature of a gas increases.
the gas particles move more quickly and the volume of the gas increases
400
the change in that from a solid directly to a gas
sublimation
400
what is the temperature at which a liquid turns into a solid.
Freezing point
400
in which state of matter does the particles move the fastest
gas
500
a form of matter that does not have a definite shape or volume.
gas
500
for Charles law what happens if the temperature of a gas decreases
the volume of the gas decreses and the particle move slower
500
what is the difference between boiling and evaporation.
the difference is evaporation happens below its boiling point and boiling point is above its boiling point.
500
what is sublimation and give me an example
when a solid turns directly to a gas EX: dry ice
500
