States of Matter Flashcards
Define Solid
A solid is a state matter that has a fixed shape and volume. Atoms are boud together
Define liquid
A liquid is a state of matter that has a fixed volume but not a fixed shape, it takes on eh shape of its container. Atmos are loosely bounded together
Define gas
Does not have a fixed shape or volume. Atoms move freely wherever they want
Define Volume
volume is the measurement of how much space is taken up by a substance or object
Define fluid
Fluid is any substance or material that will flow in response to an applied force
Define mass
Mass is the measurement of how much quanitiy of matter an object/substance has
Define particle model
A particle model is a model that descirbes how particles move around and behave in an object/substance. The model explains the properties of solids, liquids and gases.
Define Melting
Melting is where a solid is transformed into a liquid from applied heat
Define Melting point
Melting point is the temperature at which a solid begins to melt into a lquid
Define boiling
Boiling occurs when a substance is getting heated. Bubbles will occur and eb=ventually this will result in avaporation
Define evaporation
Evaporation is where a liquid transforms into a gas from applied heat and evaporates into the air
Define boiling point
the temperature at which a liquid changes to a gas
define freezing
freezing is when a liquid object/substance gets heat taken away from it and turns into a solid
define freezing point
freezing point is the temperature in which a liquid starts to solidify
define sublimation
the change in state from a solid into a gas without first becoming a liquid
Define property
characteristics or features of an object or substance
define expand
increase in size due to the movement of particles in a substance/object
define contract
decrease/shorten in size due to less movement of particles in a substance
How properties of a liquid is related to the behaviour of the particles
Liquid particles roll over each other. But they cannot ‘escape’. For this reason, they have a fixed volume, but the rolling motion allows them to take up the shape of its container
How properties of a solid is related to the behaviour of the particles
Solid particles are tightly bound together so they cannot be compressed. Bonds between particles are very strong and particles are not able to move around, exaplaining their fixed shape.
How properties of a gas is related to the behaviour of the particles
Gas particles’ attraction are so weak, they can move around freely in any direction. Gases spread out and take up any space. Gasses can be compressed because of the weak attraction of particles.
