ASAP Why are hydrogen bonds the key to the properties of water?

Adhesion how is this shown through a narrow glass tube? An example found in nature.

High surface tension how is it created and useful? Two examples in nature

Difference between high specific heat and heat of vaporization? How do the two moderate earth's climate

The first one is: The hydrogen bonds that form between water molecules account for some of the essential — and unique — properties of water. ... The attraction created by hydrogen bonds keeps water liquid over a wider range of temperature than is found for any other molecule its size.

The second one is: Before it overflows, the water forms a dome-like shape above the rim of the glass. This dome-like shape forms due to the water molecules’ cohesive properties, or their tendency to stick to one another. Cohesion refers to the attraction of molecules for other molecules of the same kind, and water molecules have strong cohesive forces thanks to their ability to form hydrogen bonds with one another.

The third one is: Water molecules want to cling to each other. At the surface, however, there are fewer water molecules to cling to since there is air above (thus, no water molecules). This results in a stronger bond between those molecules that actually do come in contact with one another, and a layer of strongly bonded water

This is the fourth: Water molecules are very good at forming hydrogen bonds, weak associations between the partially positive and partially negative ends of the molecules. Hydrogen bonding explains both the effectiveness of evaporative cooling (why sweating cools you off) and the low density of ice (why ice floats).

Explanation: i hope this helps it was a lot of typing!!!

the answer is trees if i'm not mistaken

if the type of the food available changes, then the frequency of beak types will change, because birds with beaks more suited to the available food will be more successful over time.
