C1.1 Particles and their behaviour Flashcards
what are all materials made out of
materials are made out of lots of tiny particles
What is a substances
the only have one type of particle in them unlike most materials
are most materials mixtures?
yes
every oxgyen particle is the same as another oxygen particles?
Yes
what is properties of substance?
how it looks, behaves, shape, size, how strongly its particles are held together
What are the three states of matter?
solid, liquid, gas
what is the particle model?
the model showing how a liquid, solid or gas’ particles are aranged
what is volume
the amount of space something takes up
what is density
how concentrated
how does the particle model explain density?
by how close the particles are
what is mass?
how much there is of something
how does state affect density?
because in a solid the particles are closer together meaning a higher density but in a gas the particles are far apart that means less density
formula for denisty
density = mass ÷ volume
Why is water so special and different than other substances
its solid form is loghter than its liquid form
what is the particle model for a gas look like?
particles spread out across the space
what is the law of conservation of mass
that no
what is the particle model for a liquid look like?
particles close but no stuck on the spot and can flo0w freely on top of each other
what is the particle model for a solid look like?
particles are closely compact and cannot move only can vibrate on the spot
what is the change of state from gas to solid
deposition
what is the change of state from solid to gas
sublimation
what is the change of state from liquid to gas
evaporating
what is the change of state from gas to liquid
condensing
what is the change of state from solid to liquid
melting
what is the change of state from liquid to solid
freezing
