Chapter 3 States of Matter

A graph that shows the change in temperature of a substance as it is heated will show.

• A straight line as the substance melts.
• A straight line as the substance freezes.
• A rising line as the volume increases. (Direct Variation)
• A falling line as the volume decreases. (Indirection Variation)

A drop of vinegar will flow and spread out but a drop of vegetable oil will form a bead. This is evidence that

• Vegetable oil has a lower surface tension and lower viscosity than vinegar.
• Vinegar has a lower surface tension and lower viscosity than vegetable oil.
• Vegetable oil has a lower surface tension and higher viscosity than vinegar.
• Vinegar has a lower surface tension and higher viscosity than vegetable oil.

According to Charles’s law,

• Heating a balloon will cause it to expand.
• Crushing a closed container of gas will increase the pressure.
• Pumping more air into a basketball will increase the pressure.
• Filling a balloon with helium will cause it to rise.

If you open a bottle of perfume, after a period of time, the people on the opposite side of the room will be able to smell it due to the process of

• Condensation.
• Evaporation.
• Sublimation.
• Vapor pressure.

The reverse of condensation is

• Boiling.
• Evaporation.
• Freezing.
• Sublimation.
