Water has a high specific heat capacity because it is a relatively light molecule (18 grams per mole). The specific heats of molecules are all about the same on a per-molecule basis, especially at higher temperatures. This is called the law of Dulong and Petit. At low temperatures, it gets more complicated because the vibrations of molecules are quantized.
When specific heats are measured on a per-gram basis, lighter molecules have higher specific heats. For example, the specific heat of hydrogen (H2), which has a molecular weight of 2 grams per mole, is much higher than that of water. Liquid water has a higher specific heat than most other liquids (such as alcohols) because its molecules are lighter.
What else can I help you with?
Explain how the specific heat of a substance is determined?
specific heat is the amount of heat to be absorbed required to raise a substance 1 degree celsius. And by heat being absorbed, i mean energy, because specific heat is measured in joules
What is another term used for specific heat is?
Another term used for specific heat is temperature.
What unit is specific heat measured in?
In SI, specific heat capacity is measured in joules per kilogram kelvin.
Many common metals have a specific heat of what?
There is not a common specific heat among metals. The specific heat of metals ranges from .12 J / kg K for uranium to 1.83 J / kg K for Beryllium.
How does waters heat-holding affect human beings?
It helps the body remove heat through sweating, and it also allows it to use water as an energy source.
Waters high specific heat is mainly a consequence of the?
absorbtion and release of heat when hydrogen bonds break and form
is the specific heat of coconut water and water the same?
No, the specific heat of coconut water is typically lower than that of regular water. Coconut water has a specific heat capacity of around 3.91 J/g°C, while water has a specific heat capacity of around 4.18 J/g°C.
Why are temperature near the great lakes cooler in the summer than temperatures a few miles away?
The lakes have a high specific heat capacity.Answer:Air passing over the lakes becomes moister from evaporation. This evaporation of water requires heat which is absorbed from the air. As a consequence the air becomes cooler.
What means that a large amount of energy is required to change the waters temperature?
Water has a high specific heat capacity, meaning it can absorb or release a lot of heat energy without its temperature changing much. This is why it takes a large amount of energy to raise or lower the temperature of water compared to other substances.

What is true about waters specific heat?
Water has a high specific heat capacity, which means it can absorb and release a large amount of heat without much change in temperature. This property allows water to help regulate Earth's climate by absorbing heat in the summer and releasing it in the winter.
Why specific heat is large specific volume?
Specific heat has nothing to do with specific volume.
What is the specific heat of sinter?
Specific heat of sinter
What is a normal consequence of the activation of the heat promoting centre?
sympathetic sweat gland activation
Can seahorses survive in cold waters?
they live in cold waters. sometimes though they tend to prefer it if the heat of the water is lukewarm.
Solar energy how is it used?

What factor most influence the amount of energy needed to change the temperature of a substance?
specific heat capacity
