Detailed explanation-1: -Water’s extensive capability to dissolve a variety of molecules has earned it the designation of “universal solvent, ” and it is this ability that makes water such an invaluable life-sustaining force. On a biological level, water’s role as a solvent helps cells transport and use substances like oxygen or nutrients.

Detailed explanation-2: -The excellent ability of water to dissolve so many substances allows our cells to use valuable nutrients, minerals, and chemicals in biological processes. Water’s “stickiness” (from surface tension) plays a part in our body’s ability to transport these materials all through ourselves.

Detailed explanation-3: -Discussion of the properties of water that make it essential to life as we know it: polarity, “universal” solvent, high heat capacity, high heat of vaporization, cohesion, adhesion and lower density when frozen.

Detailed explanation-4: -Water’s Polarity One of water’s important properties is that it is composed of polar molecules: the hydrogen and oxygen within water molecules (H2O) form polar covalent bonds.

Detailed explanation-5: -Water molecules have a polar arrangement of oxygen and hydrogen atoms-one side (hydrogen) has a positive electrical charge and the other side (oxygen) had a negative charge. This allows the water molecule to become attracted to many other different types of molecules.
