Which property of a glass of juice is an example of an extensive physical property? 

• weight

Which property of a glass of water is an example of an extensive physical property?

• color of water
• volume of water
• density of water
• transparency of water

Because the amount (n) and the mass (m) of a substance are both extensive properties, the molar mass (molar mass=m/n) of the substance is also an extensive property.

• true
• false

Because mass and volume are both extensive properties, density is also an extensive property?

• true
• false

Because the more water you boil the more time it will take the boiling water is an extensive physical property. 

• true
• false

The endothermic conversion in which a state of matter with definite volume and definite shape converts to a substance with indefinite volume, indefinite shape, but definite mass, without passing through the liquid state.

• melting
• freezing
• deposition
• sublimation
