Particles : Solids , Liquids , and Gases

Question 1

What is a solid?

Answer 1

A solid is made up of atoms, molecules, and/or ions. It retains its shape because the particles are locked into place.

Question 2

What is a liquid?

Answer 2

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

Question 3

What is a gas?

Answer 3

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.

Question 4

Can gas be compressed? - Why?

Answer 4

Yes. Because there is a lot of free space between the particles.

Question 5

Can liquid be compressed? - Why?

Answer 5

It is not easily compressible because there is only a little bit of free space between the particles.

Question 6

Can a solid be compressed? - Why?

Answer 6

No. Because there is barely enough space between the particles.

Question 7

Does a solid have a fixed volume and a fixed shape?

Answer 7

Volume : Yes

Shape : Yes

Question 8

Does a liquid have a fixed volume and a fixed shape?

Answer 8

Volume :Yes

Shape : No

Question 9

Does a gas have a fixed volume and a fixed shape?

Answer 9

Volume : No

Shape : No

Question 10

Why can’t a solid flow?

Answer 10

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.

Question 11

Why can a liquid flow?

Answer 11

A liquid can flow because it can change its position because it has space to over each other.

Question 12

What is Brownian Motion?

Answer 12

Brownian motion is when fluid particles push larger objects / particles and making them look like they are moving around randomly.

Question 13

What are the 4 states of scientific theories?

Answer 13

1. Make a hypothesis
2. Make a prediction
3. Test the prediction
4. Repeat the experiment

Question 14

Why is it important to repeat the experiment even though the first one might’ve worked?

Answer 14

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.

Question 15

What is diffusion?

Answer 15

Diffusion is the movement of particles that allows to spread out and mix with other particles.

Question 16

Would diffusion happen quicker gases or liquids? - Why?

Answer 16

It would be quicker in gas. Because the gas particles have more energy so they would move much quicker.

Question 17

Would diffusion happen in solids? - Why?

Answer 17

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.

Question 18

If we poured a single drop of food colouring into 2 beakers with the same amount of water, one filled with hot water and the other one with cold water, which beaker would be completely in food colouring? - Why?

Answer 18

When the temperature is warmer, there is more energy. Therefore, in cold / low temperature, there is less energy and the particles are slower. And, in high temperature the energy is so high it goes fast. It makes a quicker energy. So the beaker filled with hot water would be completely be in food colouring.
