A secondary function of the respiratory system of the mammals is, during inspiration, to heat the air to body temperature and to saturate it with water before it reaches the alveoli. Relying on a mathematical model, we propose a comprehensive analysis of this function, considering all the terres...
the BTU is the amount of energy required to raise the temperature of one pound of water from 63 to 64 °F. One BTU is approximately 252 calories. Both definitions specify that the temperature changes are to be measured at a constant pressure of one atmosphere, because the amounts of energy...
The specific heat anomaly in triethylamine–heavy water near the critical solution point The anomaly in the specific heatCpxhas been investigated by means of a constant heating rate method. Accurate results could be obtained for ‖T‐Tc‖/Tcval... E Bloemen,J Thoen,WV Dael - 《Chemical Physi...
The heat capacity at constant volume CV of pure water has been measured in the temperature range from 412 K to 693 K at 13 isochores between 250 kg·m-3 and 925 kg·m-3. Measurements cover the critical region and coexistence curve. Measurements have been made in both the one- and two...
In a water-cooled engine,running under constant conditions,20.2 kJ of heat energy is transferred from the engine to the water coolant every second.If the water is flowing at a rate of 11.5 L/min,in a closed circuit between the engine and the radiator,by what amount must the temperature ...

This process is particularly adapted to wet biomass as drying is no longer required, taking advantage of the properties of water under subcritical conditions [11,12,13]. The reduced viscosity, the dielectric constant of water and the increased reactivity facilitate the conversion of biomass. Biomass...
heat capacity—it takes less energy to raise the temperature by one degree.Because water has a high heat capacity, it requires more energy to raise the temperature by one degree. The sun puts out a more or less constant rate of energy, which heats up sand more quickly and water more ...
The molar heat capacity (C_p) of water at constant pressure is 75 J.K-1.mol-1. The increase in temperature (in K) of 100 g of water when 1 k.J. of heat is supplied to it is. ( ) A. 2.4 B. 0.24 C. 1.3 D. 0.13 相关知识点: 试题来源: 解析 A 反馈 收藏 ...
