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 high specific heat of water also helps regulate the rate at which air changes temperature, which is why the temperature change between seasons is gradual rather than sudden, especially near the oceans.
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 is an excellent solvent. Water has the unique ability to dissolve many polar and ionic substances. This is important to all living things because, as water travels through the water cycle, it takes many valuable nutrients along with it!
