Water contributes to the fitness of the environment to support life by acting as a Solvent for molecules to interact Moderate Earth's climate.
Water contributes to the fitness of the environment to support life in several ways :
- Life on Earth began in water and evolved there for 3 billion years before colonizing the land.
- Even terrestrial organisms are tied to water.
- Most cells are surrounded by water.
- Cells are about 70–95% water.
- Water is a reactant in many of the chemical reactions of life.
- Water is the only common substance that exists in the natural world in all three physical states of matter: solid ice, liquid water, and water vapour.
- Water stabilizes air temperatures by absorbing heat from warmer air and releasing heat to cooler air.
- Water can absorb or release relatively large amounts of heat with only a slight change in its own temperature.
- Water’s high heat of vaporization moderates climate.
- Much of the sun’s heat absorbed by tropical oceans is used for evaporation of surface water.
- Water is unusual because it is less dense as a solid than as a cold liquid.
- Most materials contract as they solidify, but water expands.
- At temperatures above 4°C, water behaves like other liquids, expanding as it warms and contracting as it cools.
- Water begins to freeze when its molecules are no longer moving vigorously enough to break their hydrogen bonds.
- When water reaches 0°C, water becomes locked into a crystalline lattice, with each water molecule bonded to a maximum of four partners.

#SPJ4
3 electrons would be in the 2p orbital
Answer:
B
Explanation:
because polarity of the water molecules is due to the B. deflection of the hydrogen atoms by the lone pair of electrons.
Answer:
The number of molecules is 1.4140*10^24 molecules
Explanation:
To know the number of molecules, we need to determine how many moles of water we have, water has molar mass of 18.015g/mol
This means that one mole of water molecules has a mass of 18.015g.
42.3g * 1 mole H2O/18.015g
= 2.3480 moles H2O
We are using avogadros number to find the number of molecules of water
2.3480 H2O * 6.022*10^ 23moles/ 1mole of H2O
That's 2.3480 multiplied by 6.022*10^23 divided by 1 mole of H2O
Number of molecules = 1.4140 *10^24 molecules
