During the winter, air temperatures in the northern United States can remain below 0°C for months; however, the fish and other animals living in the lakes survive.  This is due to water's

• capillary action
• density
• cohesion
• specific heat

When you pour water into a 25-mL graduated cylinder, a meniscus forms at the top of the water column.  This is due to the ________ of water.

• adhesion
• cohesion
• density
• specific heat

Water drops that fall on a surface tend to form rounded drops or beads.  This is due to the __________ of water.

• adhesion
• cohesion
• density
• specific heat

If you touch the edge of a paper towel to a drop of colored water, the water will move up into (or be absorbed by) the towel.  This is a demonstration of water's

• capillary action
• density
• ability to dissolve most substance
• specific heat

The temperature in San Francisco tends to stay the same throughout the year, but at the same latitude a land locked city's temperature with fluctuate greatly.  This is due to water's  

• adhesion
• density
• ability to dissolve many solutes
• specific heat
