heat capacity (redirected fromheat capacities) Medical Encyclopedia Related to heat capacities:specific heat capacities heat capacity n. The ratio of the heat energy absorbed by a substance to the substance's increase in temperature. Also calledthermal capacity. ...
Example:The molar heat capacity of iron is 25.10 J/(mol K), which means that it takes 25.10 Joules of heat to raise 1 mol of iron by 1 degree Kelvin. Tabulated values of molar heat capacity, Cp,of a lot of organic and inorganic substances can be found inStandard enthalpy of formation...
The article focuses on the use of cold water corals off South Australia in determining climate variation, based on studies by Sam Burgess, a Doctor of Philosophy (PhD) student at the Australian National University. Burgess used oxygen-1...

In another research, Sekhar and Sharma24, while studying the specific heat capacity of Al2O3/W nanofluid at low concentrations (0.01–1 vol%), proposed a specific heat correlation in accordance with 81 experimental data-points of water-based Al2O3, SiO2, TiO2, and CuO nanofluids collected ...
The calculated magnetic entropy showed the value of S(T) ‰ 1 J/(mol K) which is extremely small; i.e., much lower than the magnetic contribution Rln(2S + 1) = 11:52 J/(mol K) calculated for the spin 3/2. 展开 关键词: heat capacity antiferromagnetics magnetic semiconductors ...
The NTU, capacity ratio (R), and the effectiveness are inter-related. They are often presented in the form of a chart for a specfic heat exchanger; so knowing any two quantities will help find the third quantity from the chart. Then, by calculating the Cmin/Cmax and the NTU, the effe...

Take a look at the donut chart below. In 1978 (inner ring), about 80 percent of home energy use went to heating homes (66 percent) and hot water (14 percent). Today, those figures have changed quite a bit and much less of our energy (62 percent) is now used this way (heating ...
Generally, temperature decline at night reduces its water vapour holding capacity and increases dew point temperature. The higher dew point can harm public health even with a lower temperature. Studies showed that most deaths during the European heatwave in 2003 were at night38,64. This emphasizes...
