A scientific law

• is a statement that describes a consistent relationship observed in nature.

• is an opinion based on personal beliefs.

• has not been tested yet.

• describes a single event in nature.

A scientific theory

• A random guess about the natural world.
• An opinion based on personal beliefs.
• A well-substantiated explanation of the natural world.
• A hypothesis that is yet to be tested.

Why can't fatty acids dissolve in water?

• because they have to be heated

• because they are polar

• because they are nonpolar

Water is considered a universal solvent because it

• is a polar solvent that can dissolve many substances.
• is a non-polar solvent that cannot dissolve any substances.
• is only effective in dissolving gases.
• is a solid at room temperature and does not dissolve anything.

Large bodies of water do not fluctuate in temperature due to

• water's adhesive properties.

• water being nonpolar.

• water's cohesive nature.

• water's high specific heat capacity.
