What advantage does the high specific heat capacity of water have for terrestrial organisms?

Due to its high heat capacity, water is used by warm blooded animals to more evenly disperse heat in their bodies; it acts in a similar manner to a car's cooling system, transporting heat from warm places to cool places, causing the body to maintain a more even temperature.

Why is the high heat capacity of water an advantage for living organisms?

The resistance to sudden temperature changes makes water an excellent habitat, allowing organisms to survive without experiencing wide temperature fluctuation. Furthermore, because many organisms are mainly composed of water, the property of high heat capacity allows highly regulated internal body temperatures.

How does the high specific heat of water benefit marine organisms?

How does water's high heat capacity benefit/affect marine organisms? Because water has a high heat capacity marine organisms don't go through drastic changes in temperature in their environment. Why are there tides?

How does water's high specific heat affect aquatic and terrestrial ecosystems?

Water's high specific heat, high heat of vaporization, and expansion upon freezing affect ecosystems in different ways. Its high specific heat enables water to stabilize temperatures. Water's high heat of vaporization helps to control earth's climate.

What are the disadvantages of high specific heat capacity of water?

Water has high specific heat. So, it can absorb a large amount of heat without rising its temperature to a high value. But it cannot be used for measuring small temperature differences.

Why is specific heat capacity important?

Specific heat capacity is a measure of the amount of heat energy required to change the temperature of 1 kg of a material by 1 K. Hence it is important as it will give an indication of how much energy will be required to heat or cool an object of a given mass by a given amount.

What does a high specific heat capacity mean?

The higher the specific heat capacity, the smaller the temperature change for the same amount of heat applied to the same mass of substance.

How does the specific heat capacity of water protect living organisms?

The sweat on the surface of the skin absorbs heat from the skin (and thus in turn from the blood). ... Due to the fact water has a high specific heat capacity, sweat can extract a lot of heat from blood and can therefore be highly efficient at lowering an animals core body temperature.

Why is it important that water has a high latent heat of vaporization?

Water has a high heat of vaporization because hydrogen bonds form readily between the oxygen of one molecule and the hydrogens of other molecules. These bonds hold the molecules together. To get water to vaporize, you must increase the temperature to make the molecules move faster.

What has a higher specific heat than water?

On a mass basis hydrogen gas has more than three times the specific heat as water under normal laboratory conditions.

What is specific heat capacity of water?

In thermodynamics, the specific heat capacity (symbol c_p) of a substance is the heat capacity of a sample of the substance divided by the mass of the sample. ... For example, the heat required to raise the temperature of 1 kg of water by 1 K is 4184 joules, so the specific heat capacity of water is 4184 J⋅kg⁻¹⋅K⁻¹.

How does water's high specific heat contribute to the moderation of temperature?

With a high specific heat, a large body of water can absorb and store a huge amount of heat from the sun in the daytime and during summer while warming up only a few degrees. As this water generally cools during the night and during winter, it warms the air, contributing to milder climates in coastal regions.

Why do liquid water ice and water vapor have different specific heats?

As a liquid, water has more directions to move and to absorb the heat applied to it. There is more surface area that needs to be heated for the overall temperature to increase. However, with ice, the surface area doesn't change due to its more rigid structure.

Why do water molecules have high cohesion?

Cohesion refers to the attraction of molecules for other molecules of the same kind, and water molecules have strong cohesive forces thanks to their ability to form hydrogen bonds with one another. ... Thus, the water molecules at the surface form stronger interactions with the neighbors they do have.

Why is specific heat more useful than heat capacity?

For example, more energy will be needed to heat a 5 gallon tank of water 1 degree C than would be needed to heat one cup of water by 1 degree C. On the other hand specific heat capacity will be more useful because it is the amount of energy needed to raise the temperature a gram of that object by 1 degree C.

Is it better to have a high or low specific heat?

So, a high value means that it takes MORE energy to raise (or lower) its temperature. A low value means that it does not take very much energy to heat or cool it. Adding heat to a “low specific heat” compound will increase its temperature much more quickly than adding heat to a high specific heat compound.
