 Specific Heats On this slide we derive some equations which relate the heat capacity of a gas to the gas constant used in the equation of state. From our studies of heat transfer, we know that the amount of heat transferred between two objects is proportional to the temperature difference between the objects and the heat capacity of the objects. The specific heat constants for constant pressure and constant volume processes are related to the gas constant for a given gas. www.grc.nasa.gov /WWW/K-12/airplane/specheat.html   (909 words)

 Calorimetry: Specific Heat Capacity of Copper   (Site not responding.

 Specific Heat The specific heat is the amount of heat per unit mass required to raise the temperature by one degree Celsius. The specific heat per gram for water is much higher than that for a metal, as described in the water-metal example. The molar specific heats of most solids at room temperature and above are nearly constant, in agreement with the Law of Dulong and Petit. hyperphysics.phy-astr.gsu.edu /hbase/thermo/spht.html   (319 words)

 Kids.Net.Au - Encyclopedia > Specific heat capacity Specific heat capacity is the slope (derivative) of the internal energy due to random motion of atoms in a sample as a function of temperature, normalized by dividing by the mass of the sample. Because the internal energy curve is normally almost linear, it can by approximated by measuring the heat required to raise the temperature of 1 kg of a substance by 1°C (or one Kelvin). If a fluid has stronger intermolecular forces (such as hydrogen bonding in water) then the heat capacity is likely to be higher. www.kids.net.au /encyclopedia-wiki/sp/Specific_heat_capacity   (151 words)

 Heat capacity - Wikipedia, the free encyclopedia Heat capacity (usually denoted by a capital C, often with subscripts) is a measurable physical quantity that characterizes the ability of a body to store heat as it changes in temperature. The dimensionless heat capacity divided by three, as a function of temperature as predicted by the Debye model and by Einstein's earlier model. One of the strengths of the Debye model is that (unlike the preceding Einstein model) it predicts an approach of heat capacity toward zero as zero temperature is approached, and also predicts the proper mathematical form of the this approach. en.wikipedia.org /wiki/Heat_capacity   (1967 words)

 Heat Capacity   (Site not responding. Last check: ) The heat capacity of an object is the ratio of the amount of heat transferred to an object to the rise in temperature of an object. Because water's heat capacity is large, it doesn't change temperature much upon absorbing large amounts of heat energy from the sun when compared to the temperature change predicted for air. Note that the specific heat of water is more than 4 times that of an equal quantity (by mass) of air {realize, of course, that these are not equal volumes of water and air}. hendrix.uoregon.edu /~stanm/phys162s2003/PHYS162/Heat_Capacity.html   (291 words)
