Solids
Have a definite _____________ and ______________
Shape and Volume
Have a definite _____________________
Volume
Gases have no definite __________________ or ___________________
Shape or volume
What happens to particles as we add heat to them?
They speed up, and need more space between them
What are atoms made of? (looking for 3 things)
Protons, Neutrons, Electrons
What do the particles in solids act like?
Slow, vibrate in place, don't move much.
What do the particles in liquids act like?
Kind of fast, stick together a bit, slip around each other
What do particles in gases act like?
FAST, very far apart, bump into and bounce off things
Describe a situation that would be VERY high pressure (3 things that would make it high pressure)
TONS of particles, in a small box, with a high temperature
What is the charge of a proton?
Positive
Which type of solid is "organized"?
Bonus shot: What is an example of one we have talked about in class?
Crystalline, the particles are in a pattern
Salt, Diamonds
What is viscosity? Give an example of something with HIGH viscosity.
A liquids resistance to flow, corn syrup.
HOW do gases apply pressure to a container?
By hitting the sides of the container.
Explain Attractive Forces
They are something that attract the particles in a substance together. Some substances have stronger attractive forces than others.
What is the charge of a neutron?
Neutral (no charge)
Which type of solid means "having no shape or form"?
Bonus shot: What is an example of one we have talked about in class?
amorphous
Coal
What is surface tension? Explain it on a particle level.
Molecules stick together, and create a weak platform that can have pressure put on it.
What does Charles's Law state?
If temperature increases, volume or pressure increases.
What two things do we need to have the strongest attractive forces? Think about what the particles need to be doing.
Slow particles, close together
What is the charge of an electron?
Negative
AWV
Put a balloon in warm water, and watch it expand (temp increases, so volume increases so pressure doesn't)
Explain how the attractive forces are in solids, and why they are that way.
Strong, because the particles are slow and close together
Explain how the attractive forces are in liquids, and why they are that way.
Kind of weak, the particles are a bit fast so they stick together for a bit, and they are a bit spread out.
Explain how the attractive forces are in gases, and why they are that way.
Weak, because the particles are moving very quickly and are very far apart
Why doesn't temperature change when ice is melting, or boiling? (in an ideal lab)
All of the energy goes towards breaking the molecules up and speeding them up, rather than making the substance warmer
What is something that is always different between EVERY different kind of atom?
For example, what is something that is different between Hydrogen, Helium, Boron, and Carbon?
The number of protons
What is the equation for pressure?
Force divided by area
Force over area
