Question

1. now, please complete the interactivity by clicking on one of the states of matter and then its 2 pictures (1 real-life and 1 smaller microscopic)

lets review...

1. true or false - the volume of solids cannot be changed due to the strong particle attraction.
2. true or false - liquids possess definite volume, but not shape.
3. a solid is that form of matter that possesses the following characteristics

a) definite shape c) particles vibrate around fixed axes
b) definite volume d) all of the above

1. a gas has no definite

a) shape c) weight
b) volume d) both a and b

1. which of the following best explains why solids do not change much when pressure is applied to them?

a) the particles in a solid have large spaces between them
b) the particles in a solid keep vibrating
c) the particles in a solid are packed very close to each other
d) none of the above

1. which of the following is/are the characteristic(s) of solids?

a) a definite shape c) incompressibility
b) a definite volume d) all of the above

1. the water cycle is a complex system. in it, water changes states. sometimes it is a liquid, sometimes it is a solid, while other times it can become a gas. what change occurs when water is boiled?

a) liquid becomes a gas c) gas becomes a liquid
b) solid becomes a liquid d) gas becomes a solid

1. solids have a definite

a) shape c) arrangement of atoms, molecules
b) volume d) all of the above

Explanation:

1. Solids have strong particle attraction, so their volume is difficult to change.
2. Liquids have a definite volume but take the shape of their container.
3. Solids have definite shape, definite volume, and particles vibrate around fixed axes.
4. Gases have no definite shape or volume.
5. Solids' particles are closely packed, so they don't change much under pressure.
6. Solids have definite shape, definite volume, and are incompressible.
7. Boiling water changes it from liquid to gas.
8. Solids have definite shape, volume, and arrangement of atoms/molecules.

Answer:

1. True
2. True
3. d) All of the above
4. d) Both A and B
5. c) The particles in a solid are packed very close to each other
6. d) All of the above
7. a) Liquid becomes a gas
8. d) All of the above
