Water is essential for life. Its special properties make water the single most important molecule in plant life. Which of the following properties of water enables it to move from the roots to the leaves of plants?

Water is able to moderate temperature.

Water has a much higher specific heat than most other covalent compounds. What do you predict might happen if water had a low specific heat instead?

Organisms that are sensitive to changes in temperature would die

Flooding would occur and animals would be forced to migrate

Harmful organisms living in water would reproduce at a rapid rate

Plants would not have enough water to effectively carry out photosynthesis

A high specific heat means...

It requires more energy to change temperature

It heats up quickly with energy added

Which of the following best explains why the sand at the beach is hotter than the water?

Sand has a lower specific heat than water, requiring less energy to heat up than water.

Sand has a higher specific heat than water, requiring more energy to heat up than water.

Sand has a greater mass than water.

Water has a greater mass than sand.

Sweating helps us with homeostasis because as sweat evaporates

a lot of heat is carried away and we cool down

we increase surface tension which cools us down

the water seeps into our pores and we cool down

Living things are mainly water. Water has a HIGH SPECIFIC HEAT (heat capacity). This helps with homeostasis because living things can

absorb a lot of heat before changing temperature

easily change temperature depending on their environment

This picture shows the polarity of water because

oxygen holds the shared electrons closer and becomes negative

hydrogen holds the shared electrons closer and becomes negative

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.
