Particles Flashcards
What is the process of water to steam?
Evaporation
What is the process so ice to water?
Melting
What is the process steam to water ?
Condensing
What is the process of water to ice ?
Freezing
What state of led would it be in if it’s put in the oven?
It would be a solid and wouldn’t melt because it’s melting point is really high
What are the three states of matter?
Sold liquid and gases
The particles are in - positions. Solids can not be - . Solids have fixed -.
Fixed compressed volumes
The particles can move - one another but cannot -. Liquids have fixed volume but can be -.
Past escape poured
What is it if the particle diagram is irregular?
Liquid
What is gas pressure?
It’s when the particles are vibrating and colliding into each other and the walls of the container
Would adding more air into a container increase the pressure or decrease it?
It increases the pressure because adding more particles cause more frequent collisions into the walls
Is it the higher the pressure the higher temp?
Yes
At what temperature does water boil
100 ‘c
Solid - liquid - gas - liquid - solid
Melting evaporating condensing freezing
What can’t you do with a solid?
You can’t compress a substance or make it flow
What can’t you do with a liquid?
You can’t compress a substance but you can make it flow
What can you do with a gas that you can’t do with a solid and liquid?
You can compress a substance and make it flow
What is the difference between evaporating and boiling?
Boiling: it can only happen at the boiling point (100’c)
Evaporation: it can happen at any temperature
How can a liquid Change into gas ?
By evaporating or boiling
What temperature does water boil at ?
100’c
Why when you take a bottle full of air (that has caved in) out of the freezer does it pop out?
Because when you take it out (warms up) the particles vibrate more and it crashes into the wall more so it causes more gas pressure
What is it called when a solid goes straight into gas?
Subliming
What causes gas pressure?
Gas particles colliding with the walls and each other exert on pressure on the container
Does adding more air increase the pressure?
Yes because adding more particles cause more frequent collisions into the walls
Think in you head what a graph looks like and how you would do it
Have you done it ,good
When the water boils do the particles stay together?
The particles stay together but when it starts to boil the particles move away from each other
Do particles stay the same size when they boil?
Yes they do
