Flashcards in Particles : Solids , Liquids , and Gases Deck (18):
What is a solid?
A solid is made up of atoms, molecules, and/or ions. It retains its shape because the particles are locked into place.
What is a liquid?
A liquid is made up of atoms, molecules, and/or ions. It assumes the shape of the part of the container which it occupies. The particles can move/slide past one another
What is a gas?
A gas is made up of atoms, molecules, and/or ions. It assumes the shape and volume of its container.
particles can move past one another because the particles are spread out.
Can gas be compressed? - Why?
Yes. Because there is a lot of free space between the particles.
Can liquid be compressed? - Why?
It is not easily compressible because there is only a little bit of free space between the particles.
Can a solid be compressed? - Why?
No. Because there is barely enough space between the particles.
Does a solid have a fixed volume and a fixed shape?
Volume : Yes
Shape : Yes
Does a liquid have a fixed volume and a fixed shape?
Shape : No
Does a gas have a fixed volume and a fixed shape?
Volume : No
Shape : No
Why can't a solid flow?
A solid can't flow because the particles can't move from place to place since they are so packed together, they can only vibrate.
Why can a liquid flow?
A liquid can flow because it can change its position because it has space to over each other.
What is Brownian Motion?
Brownian motion is when fluid particles push larger objects / particles and making them look like they are moving around randomly.
What are the 4 states of scientific theories?
1. Make a hypothesis
2. Make a prediction
3. Test the prediction
4. Repeat the experiment
Why is it important to repeat the experiment even though the first one might've worked?
The area or substance around it could create the product or result instead of the experiment. So you need to test it again to make sure.
What is diffusion?
Diffusion is the movement of particles that allows to spread out and mix with other particles.
Would diffusion happen quicker gases or liquids? - Why?
It would be quicker in gas. Because the gas particles have more energy so they would move much quicker.
Would diffusion happen in solids? - Why?
Diffusion doesn't occur in solids because the particles in the solids are too close together to even move around and there is barely enough space.
