21. To describe a solid, which is incorrect statement:

1. The particles of a solid are attracted to each other
2. The particles of a solid can move past one another
3. The particles of a solid vibrate but do not move past one another
4. A solid has mass and takes up space

22. Two gases with unequal masses are injected into opposite ends of a long tube at the same time and allowed to diffuse toward the center. They should begin to mix

1. in approximately five minutes.
2. closer to the end that holds the heavier gas.
3. closer to the end that holds the lighter gas.
4. exactly in the middle.

23. Water drops stay together on wax paper and they don’t break apart easily. This is mainly because:

1. Water molecules are small
2. Water molecules are in motion
3. Water molecules are attracted to each other
4. Water molecules are wet

24. When a thermometer is cooled, the red liquid inside the thermometer moves down. This is mainly because:

1. Cold liquids sink
2. The glass of the thermometer gets cold
3. The molecules of the liquid move slower and get a little closer together
4. The red liquid is thick

25. When a thermometer is heated, the red liquid inside the thermometer moves up. This is mainly because:

1. The red liquid is thin.
2. The molecules of the liquid move faster and get a little further apart
3. Hot liquid is lighter
4. The glass of the thermometer gets hot

26. When energy as heat is applied to a liquid-vapor system at equilibrium, a new equilibrium state will have

1. a higher percentage of liquid.
2. a higher percentage of vapor.
3. equal amounts of liquid and vapor.
4. all liquid.

27. When you bring two drops of water near each other and allow them to touch, they combine immediately and become one drop. This is mainly because:

1. Water molecules are made of atoms
2. Water molecules are attracted to each other
3. Water molecules are magnetic
4. Water is a liquid

28. When you heat a sample of a solid, the particles that make up the solid:

1. Get bigger
2. Loose mass
3. Move faster
4. Slow down

29. When you heat a sample of a solid, the sample gets a little bigger. This is mainly because:

1. The particles move faster and get a little further apart
2. Heat helps the particles grow
3. Heating the sample makes it lighter
4. Heating helps the particles slide past each other

30. When you heat a sample of gas, what happens to the particles that make up the gas?

1. The particles move faster
2. The particles break apart
3. The particles get smaller
4. The particles become more dense
