Why does ice float?

• As water freezes, it expands and its density decreases.
• As water freezes, it takes up more hydrogen from the atmosphere, causing it to have a greater buoyancy.
• As water freezes, air becomes trapped between the hydrogen bonds of water molecules.
• As water freezes, it takes up more oxygen from the atmosphere, causing it to have a greater buoyancy.

Water is a universal solvent because it...

• It can be found anywhere
• It freezes when it gets cold
• floats when frozen
• Dissolves most substances

The fact that ice floats on liquid water is due to the fact that water's solid is ___________ than it's liquid form

• less dense
• more dense

A general definition of cohesion is the attraction of:

• particles of the same substance
• particles of a different substance
• particles of both the same and different substances
• particles of neither the same or different substances

Which term refers to water having partial positive and a partial negative charge?

• cohesion
• surface tension
• polarity

A high specific heat means...

• It heats up quickly with energy added
• It requires more energy to change temperature
