Because of water’s high heat of vaporization
Which properties of water allows dogs to cool themselves by panting?
| Question Answer | Which property of water allows dogs to cool themselves by panting? water’s high heat of vaporization | Why does ice float in liquid water? Hydrogen bonds stabilize and keep the molecules of ice farther apart than the water molecules of liquid water. |

What is the difference between H concentration in an acidic solution such as lemon juice and a basic solution such as household bleach?
What is the difference between H+ concentration in an acidic solution such as lemon juice (pH 2 ) and a basic solution such as household bleach (pH 13)? The H+ concentration of lemon juice is higher than the H+ concentration of household bleach by a factor of 1011 (100 billion).
Which property of water allows a paper towel to pick up a puddle of water?
Which property of water allows a paper towel to pick up a puddle of water? Water adheres to the cellulose molecules in a paper towel , allowing the towel to pick up a puddle of water. This is similar to the adhesion between water molecules and cellulose in cell walls responsible for water transport in plants.
Which of the following properties of water enables water molecules to stick to your coat or your shoes?
Cohesion is a property of water that enables the high surface tension.
Is dissociation of water reversible?
For example, in pure water some of the molecules dissociate to form hydrogen ions and hydroxyl ions. Dissociation is generally reversible ; when the atoms or ions of the dissociated substance are returned to the original conditions, they recombine in the original form of the substance.
Why do humans sweat and dogs pant base your answer on the unique properties of water?
Humans and dogs must maintain a constant body temperature to stay healthy . When we get hot, we sweat and are cooled by perspiration evaporating from our skin. Dogs and cats sweat least of all domestic species. Instead, dogs pant to cool themselves when they get hot.
Which of the following helps most to explain why water has a high specific heat?
Water’s high heat capacity is a property caused by hydrogen bonding among water molecules . When heat is absorbed, hydrogen bonds are broken and water molecules can move freely. When the temperature of water decreases, the hydrogen bonds are formed and release a considerable amount of energy.
What is the charge on a hydronium ion?
The hydronium ion is represented by the chemical formula H30+. This means that the hydronium ion has a charge of +1 .
When a substance has a pH of 10 it means the solution is?
For example, pH 10 is ten times more alkaline than pH 9 and 100 times (10 times 10) more alkaline than pH 8. Pure water is neutral. But when chemicals are mixed with water, the mixture can become either acidic or basic. Examples of acidic substances are vinegar and lemon juice.
What two properties of water are responsible for capillary action?
Capillary action occurs because water is sticky, thanks to the forces of cohesion (water molecules like to stay close together) and adhesion (water molecules are attracted and stick to other substances).
What is adhesive and cohesive properties of water?
Adhesion and cohesion are important water properties that affects how water works everywhere, from plant leaves to your own body. Just remember... Cohesion: Water is attracted to water , and Adhesion: Water is attracted to other substances.
Which of the following is a property of liquid water?
Water is a liquid at standard temperature and pressure (25 degrees Celsius and 1 atm, for liquids). Water is is tasteless and odorless . Water is transparent in the visible part of the electromagnetic spectrum. Water can act as either an acid or a base.
What are three properties of water that make it important for life?
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 .
What are the 5 unique properties of water?
- Water is polar. ...
- Water is an excellent solvent. ...
- Water has high heat capacity. ...
- Water has high heat of vaporization. ...
- Water has cohesive and adhesive properties. ...
- Water is less dense as a solid than as a liquid.
What are special water properties?
The unique physical properties, including a high heat of vaporization , strong surface tension, high specific heat, and nearly universal solvent properties of water are also due to hydrogen bonding.
