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.

• Hydrogen bonds between water molecules.
• polarity.
• high specific heat capacity.

Water is "sticky" because...

• of cohesion.

• of adhesion.

• of the attraction between the positively charged hydrogen atoms and the negatively charged oxygen atom.

• of capillary action.

Why does water have a high specific heat index?

• It requires a great amount of energy for water to become hot. 
• It takes water little energy to get hot.
• Water changes temperature very easily. 
• Water warms up fast when heated by the sun.

When water molecules stick to each other because of the polar attraction between hydrogen and oxygen atoms, it is called ______________.

• adhesion

• cohesion

• specific heat index

• properties of water

Water traveling up a plant is what property of water?

• surface tension

• cohesion

• specific heat index

• capillary action

Why can fish survive winters in a pond?

• ice is less dense than liquid water so it will be on the top of a lake or pond allowing fish to swim beneath it

• water is available in all 3 phases so ice will be on the top of a lake or pond allowing fish to swim beneath it

• water is polar so ice will be on the top of a lake or pond allowing fish to swim beneath it

• Adhesion so ice will be on the top of a lake or pond allowing fish to swim beneath it
