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.

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.
What is a penny's specific heat capacity?
Specific heat capacity is heat capacity per unit mass. So it depends on the exact alloy composity of your penny, and not on its size.In a typical US post-1962 penny, the specific heat capacity is about .39 kJ/kgKIn a US penny from 1864-1962, the specific heat capacity would be a little less than this. The same was true from 1837-1857.From 1793-1837, the specific heat capacity was about .39 kJ/kgK.
Waters high specific heat is mainly a consequence of the?
absorbtion and release of heat when hydrogen bonds break and form
What means that a large amount of energy is required to change the waters temperature?
Specific heat
Why is waters specific heat capacity 1.00 cal g C or 4.185 Joules g?
This is water's specific heat capacity because this is the amount of energy needed to heat up the water 1 degree Celsius.
What is true about waters specific heat?
Water must to absorb 4,184 Joules of heat for the temperature of one gram of water to increase 1 degree Celsius (°C).
is the specific heat of coconut water and water the same?
You can expect them to be similar, since coconut water is mainly water.
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.

Specific heat and latent heat of LPG?
specific heat of lpg
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
Specific heat of rice?
rice specific heat
Effect of temperature on specific heat of material?
The effect of temperature on specific heat of material is referred to as specific heat capacity.
