Question

physical property
__1. melting point
d2. thermal conductivity
a3. density
f4. magnetic property
g5. solubility
c6. boiling point
b7. electrical conductivity

what it means
a. the amount of matter in a given volume
b. a material’s ability to conduct an electric current
c. the temperature at which a substance changes from a liquid to a gas
d. it is the property of a material to conduct heat
e. the temperature at which a substance changes from a solid to a liquid
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

Explanation:

1. Melting Point: The definition of melting point is the temperature at which a substance changes from solid to liquid, so it matches E.
2. Thermal conductivity: Thermal conductivity is about a material's ability to conduct heat, so it matches D.
3. Density: Density is defined as the amount of matter in a given volume, so it matches A.
4. Magnetic property: Magnetic property involves the force between magnets or magnet and iron - related materials, so it matches F.
5. Solubility: Solubility is the ability to dissolve in another substance, so it matches G.
6. Boiling point: Boiling point is the temperature at which a substance changes from liquid to gas, so it matches C.
7. Electrical conductivity: Electrical conductivity is a material's ability to conduct an electric current, so it matches B.
