• -life adapts to its environment through natural selection
• -for life to exist at all, the environment must first be a suitable abode

• water
• -solid, liquid, gas

-70-95 percent of water

• - v shaed
• -polar molecule (two ends of the molecule have opposite charges
• -hydrogen joins to oxygen (which is more electronegative) in a single covalent bond
• -they spend more time closer to oxygen making it polar covalent bonds

hydrogen bond

• -cohesion
• -adhesion
• -surface tension
• -high specific heat

the property that waterr molecules will stick together

-collively, the hydrogen bonds hold the substance together.

-such as droplet formations

-the transportation of water and dissolved nutrients against gravity in plants

the property that water will stick to other polar or charged substances

-surface tension is the measure of how difficult it is to stretch or break the surface of a liquid.

-such as the water striders ability to walk on water due to the collective strength of the hydrogen bonds

-water standing above the rim of a slightly over filled glass of water

- the measure of heat intensity that represents the average kinetic energy of the molecules, regardless of volume.

- the swimming pool has a greater volume thana pot of coffee although the coffee has a higher temperature

freezes at 0 degrees celsius and boils at 100 degrees celsius
