WebHeat capacity is defined as the amount of heat energy required to raise the temperature of a given quantity of matter by one degree Celsius. Heat capacity for a given matter depends on its size or quantity and hence it is an extensive property. The unit of heat capacity is joule per Kelvin or joule per degree Celsius. Mathematically, WebThe higher the ratio CP/CV, the faster the speed of sound. The ratio is generally given the symbol γ: (8.2.1) C p C v = γ. Apart from any other reason, one reason for its importance is that the ratio is easier to measure precisely than either heat capacity separately. For example, you could determine it from a measurement of the speed of ... WebThe ortho–para conversion heat of hydrogen is considered by using heat capacity data of equilibrium hydrogen. Genetic algorithm-based optimization was also conducted to minimize the energy consumption of each configuration, and the optimization results showed that the performance of configuration 1 was worse than that of the base case configuration. cpi australia 2020 %
