Question

physical property | what it means
_e_ 1. melting point | a. the amount of matter in a given volume
__ 2. thermal conductivity | b. a material’s ability to conduct an electric current
__ 3. density |
| c. the temperature at which a substance changes from a liquid to a gas
__ 4. magnetic property | d. it is the property of a material to conduct heat
__ 5. solubility | e. the temperature at which a substance changes from a solid to a liquid
__ 6. boiling point | f. it is a force between two magnets or between a magnet and something made of iron.
| g. the ability to dissolve in another substance
__ 7. electrical conductivity

Explanation:

1. Melting Point: E (matches the definition of solid to liquid temperature change).
2. Thermal conductivity: D (defines heat - conducting ability of a material).
3. Density: A (is the amount of matter per unit volume).
4. Magnetic property: F (relates to the force between magnets or magnet and iron - based objects).
5. Solubility: G (is the ability to dissolve in another substance).
6. Boiling point: C (is the temperature for liquid - to - gas phase change).
7. Electrical conductivity: B (is a material's ability to conduct electric current).

Answer:

1. D
2. A
3. F
4. G
5. C
6. B
