The cooling effect of perspiration as it evaporates from the skin is the result of high of water?
Enthalpy of vaporization
What is the 6 properties of water?
universal solvent cohesion-water forms hydrogen bonds with other water molecules Ex. surface tension adhesion- water forms hydrogen bonds with other polar molecules Ex capillary action High specific heat capacity- hydrogen bonding causes water to absorb heat before its temp increases or lose heat before its temp decreases Ex. temp modification High specific heat vaporization- hydrogen bonding in liquid water causes it to absorb large amounts of heat in order to become a vapour Ex. cooling through evaporation (dog panting) Solid water is less dense than liquid water- highest density is at 4 degrees celcius, water begins to freeze crystals form making v-shaped molecules hydrogen bonding causes these vshaped molecules to spread apart making the solid water less dense Ex. Ice floats on water
How does the structure of water water relate to one of its unique properties?
The polar covalent bonds that make up the structure of water are responsible for surface tension and adhesion characteristics found in water. The bonds are also responsible for the high heat of vaporization.
Why water is ued to nextinguish fire?
Water is used to put out a fire because, it tends to cut off the oxygen that is feeding the fire and, because it has a high heat of vaporization into steam, it rather rapidly cools the burning pieces. Additionally, usually, it's readily available.
How does heat capacity makes water a good heat sink?
If a body of water has a high heat capacity, it can store more thermal energy making it a good heat sink.
Why does sweat cool off the body?
Water has a high heat of vaporization
Does water have a low vapor pressure?
High heat of vaporization. It requires a great deal of energy to break the H bonds in water.
Why does water have a relatively high boiling point and heat vaporization?
Because of strong hydrogen bonding.
Water has a high blank which causes it to heat very slowly?
water has a high which causes it to heat very slowly ?
How does the high heat of vaporization facilitate life?
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.
Desert rabbits are adapted to the warm climate because their large ears aid in the removal of heat by?
high heat of vaporization of water.
Which property of water is demonstrated when we sweat?
if what i think your trying to ask its called condincation
Why is water used in household radiators instead of oil?
Water is used in household radiators instead of oil because of high specific heat and high heat of vaporization. Water is also cheaper than oil.
Desert rabbits are adapted to the warm climate because their large ears aid in the removal of heat due to the?
high heat vaporization of water
When trees transpire releasing gaseous water into the atmosphere they can absorb heat from their environment and cool it down What property of water is responsible for this activity?
heat hight of vaporation
Does Water molecules dissociate to form h o2 ions?
Water's high heat of vaporization allows it to cool us off when we sweat
What is a unique property of water Describe the property and explain the chemical or physical reason that causes water to have the property?
Hydrogen bonding causes water molecules to connect . The energy required to break multiple hydrogen bonds causes water to have a high heat of vaporization; that is, a large amount of energy is needed to convert liquid water, where the molecules are attracted through their hydrogen bonds, to water vapor, where they are not.
