What is the property of high specific heat?

Answer 1

Heat capacity varies at different temperatures. At room temperature, the highest heat capacities known are: hydrogen gas -- 14.3 J/K/g water vapour -- 7.3 J/K/g helium gas -- 4.3 J/K/g liquid water -- 4.2 J/K/g

Answer 2

The specific heat is the amount of heat per unit mass required to raise thetemperature by one degree Celsius. The relationship between heat and temperature change is usually expressed in the form shown below where c is the specific heat. The relationship does not apply if a phase change is encountered, because the heat added or removed during a phase change does not change the temperature.

The specific heat of water is 1 calorie/gram °C = 4.186 joule/gram °C which is higher than any other common substance. As a result, water plays a very important role in temperature regulation. The specific heat per gram for water is much higher than that for a metal, as described in the water-metal example. For most purposes, it is more meaningful to compare the molar specific heats of substances.

The molar specific heats of most solids at room temperature and above are nearly constant, in agreement with the Law of Dulong and Petit. At lower temperatures the specific heats drop as quantum processes become significant. The low temperature behavior is described by the Einstein-Debye model of specific heat.

Answer 3

High Specific Heat Capacity is when a substance takes a long period of time to heat up, and cool down. Example: A hot sandy beach. It takes about 12 hours to heat the beach to a reasonable temperature. But would take 12 hours to cool down, the shore line cools faster because the water hits the hot sand and absorbs the heat and causes evaporation.

Answer 4

A substance with a high specific heat capacity is one that needs a lot of heat energy pumped into it in order to raise its temperature.

Substances with relatively high specific heat capacities include water, rock, and potatoes.

Answer 5

Hard to make it hot and hard to cool it down.

Answer 6

water has a high specific heat so that it takes a lot longer for it to heat up and to cool way down

Answer 7

Water is an example of unusually high specific heat. XP

Answer 8

If a body has high specific heat capacity then the body can absorb a lot of heat energy without itself rising to a relatively high temperature.

Answer 9

The specific heat is a material property: the heat necessary the change the temperature of a mole or a kg (or g) with 1 oC.

Answer 10

It means that a large quantity of thermal (heat) is energy is required to raise the temperature of the object compared to another object of the same mass.
