The high heat of vaporization, the implication being of water, facilitates life by allowing for efficient heat transfer from an organism to the environment during overheating. This is the case for sweat in terrestrial animals, which evaporates from the skin of a warm animal. The high heat of vaporization forces the outermost layers of the epidermis to lose the equivalent amount of thermal energy, cooling the skin.

Water molecules can bond to other water molecules by hydrogen bonding?
Not only can they, but in the liquid state they do so continuously. Hydrogen bonding between water molecules gives it many of its unique properties, such as being a liquid at standard conditions, which is essential for life; high heat capacity and heat of vaporization; and the fact that solid water is less dense than liquid water.
The ocean has a high specific heat what would happen if the ocean had a low specific heat?
If the ocean had a low specific heat it wouldn't be able to support life. This is because the water would be too cold.
The of water molecules and the hydrogen bonds between water molecules explain most of the waters life supporting properties?
Water is a polar molecule with several unique properties: its high specific heat, the high heat of vaporization, the process of evaporative cooling, and it's strong surface tension are all emergent from the formation of hydrogen bonds.
What element is the human body's first choice for fuel to facilitate life processes?
sugar
Why do people need heat?
Heat is important because we need the right amount of it. Temperatures below freezing can damage plant and animal life. Temperatures too high can also kill plant and animal life.
Describe some important propeties of water?
Water is an important compound and necessary for life on Earth. It composes about 75% of the human body. In addition, water is known as the 'universal solvent,' has a high specific heat capacity and heat of vaporization, is polar, has a high surface tension, and can act as either an acid or base in solvent. Other important properties exist, and the list is quite extensive.
Why does high specific heat of water make it essential to life?
The high specific heat allows water to act as a heat sink. Water will retain its temperature after absorbing large amount of heat and retain its temperature after losing equally large amount of heat. So water is essential for life.
What are 4 unique properties of water that make life on earth possible?
Water's Boiling Point and Freezing Point.Water's Surface Tension, Heat of Vaporization, and Vapor Pressure.Its Viscosity and Cohesion.It's available in all the 3 States (Solid, Liquid & Gas).

What properties of water protect organism that live underwater?
The properties of water that support life are solvency, cohesion and adhesion, high surface tension, high heat capacity, high heat of vaporization, and varying density. ( Mader, p.24). Among these properties, the high heat capacity is known for being important to aquatic organisms. ( Mader, p.26). Waters ability to hydrogen bond is also critical. When it freezes, water gets lighter and floats unlike the vast majority of other liquids. If it did not have this property, the ice would sink and gradually all the oceans and water sources would freeze over and not be able to sustain aquatic life. References Aquatic Animal.

How serious is heat stroke?
Heat stroke can be life threatening and because the percentage of victims dying from heat stroke is very high, immediate medical attention is critical when problems first begin.

Immediate life threatening emergency caused by extremely high body temperature and the inability to sweat?
heat stroke
What is the life span of a squid?
1-2 years, on average
Why is high specific heat importamt to life?
Water has a high specific heat due to hydrogen bonding, which increases intermolecular forces between molecules
What is the body's first choice for fuel to facilitate life processes?
Carbohydrates is the preferred fuel.
