b) Melting point
c) Mass
d) Boiling point
4. What happens to the particles of a solid as it is heated?
a) They move closer together
b) They move freely
c) They vibrate more rapidly
d) They stop moving
5. Which of the following is true about gas?
a) It has a definite shape but not a definite volume.
b) Its particles are tightly packed together.
c) It fills the entire volume of its container.
d) It has a fixed volume.
#### Section B: True/False (1 point each)
6. ___ Mass is a measure of the amount of matter in an object.
7. ___ Liquids have a definite volume but take the shape of their container.
8. ___ The boiling point of a substance is the temperature at which it becomes a solid.
9. ___ Temperature is a measure of the average kinetic energy of particles in a substance.
10. ___ An element is a pure substance made of two or more different types of atoms.
#### Section C: Short Answer (2 points each)
11. Define viscosity and provide an example of a fluid that has high viscosity.
12. Explain the difference between an element and a compound.
13. Describe the process of sublimation and give an example of a substance that undergoes this change.
#### Section D: Problem Solving (3 points each)
14. A block of wood has a mass of 200 grams and occupies a volume of 400 cm³. Calculate the density of the wood.
15. If you heat a liquid from 30°C to 80°C, what phase change might occur if its boiling point is 70°C? Describe what happens to the liquid at the boiling point.

### Answer Key
#### Section A:
1. c
2. a
3. c
4. c
5. c
#### Section B:
6. True
7. True
8. False
9. True
10. False
#### Section C:
11. Viscosity is a measure of a fluid's resistance to flow. An example is honey.
12. An element is a pure substance made of one type of atom, while a compound is made of two or more elements chemically bonded together.
13. Sublimation is the process where a solid turns directly into a gas without passing through the liquid state. An example is dry ice (solid carbon dioxide).
#### Section D:
14. Density = Mass/Volume = 200 g / 400 cm³ = 0.5 g/cm³
15. At 70°C, the liquid will reach its boiling point and start to vaporize, changing from liquid to gas as it absorbs heat.
