What is the specific heat capacity of an ideal gas?

Specific Heat for an Ideal Gas at Constant Pressure and Volume. This represents the dimensionless heat capacity at constant volume; it is generally a function of temperature due to intermolecular forces. For moderate temperatures, the constant for a monoatomic gas is cv=3/2 while for a diatomic gas it is cv=5/2 (see ).

Why should a negative value for heat capacity be set to zero?

Why should a negative value for heat capacity be set to zero? Zero heat capacity means an infinitesimally small amount of energy will increase the temperature by an infinitely large amount. An object has a non-zero heat capacity because it has internal degrees of freedom that it can channel absorbed energy into.

Which liquid has highest heat capacity?


What material has a higher heat capacity than water?

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

Which metal conducts heat the fastest?

Which Metals Conduct Heat The Best? As you can see, out of the more common metals, copper and aluminum have the highest thermal conductivity while steel and bronze have the lowest. Heat conductivity is a very important property when deciding which metal to use for a specific application.

Does concrete has a higher heat capacity than water?

Water needs over four times more heat to rise in temperature than either concrete or brick (Fig. 2). This means that water has the capacity to “absorb” more heat than other typical types of thermal mass.

Is a higher specific heat capacity better?

Specific heat is defined by the amount of heat needed to raise the temperature of 1 gram of a substance 1 degree Celsius (°C). Water has a high specific heat capacity which we’ll refer to as simply “heat capacity”, meaning it takes more energy to increase the temperature of water compared to other substances.

Does higher specific heat mean higher temperature?

Explanation: Specific heat is Jg−oK . So, a high value means that it takes MORE energy to raise (or lower) its temperature. Adding heat to a “low specific heat” compound will increase its temperature much more quickly than adding heat to a high specific heat compound.
