The method comprises the following steps of: substituting all or some measured value of each measurement system of the device into a refrigerating capacity computing formula, so that not only can the technical index of each measurement system be respectively evaluated, but also the refrigerating ...
cpa=specificheatofdryair=1.005kJ/kgK (1.12)h1=1.005t Similarly, the sensible heat of the moisture content h2 is given by: h2=gcpst−0 where: cpa=specificheatofwatervapour=1.89kJ/kgK (1.13)h2=1.89gt The water vapour is considered to have evaporated at 0°C, and therefore the latent he...
The accurate stagnation point heat transfer prediction is one of the most outstanding achievements by the classical viscous hypersonic flow theory. The compressible boundary-layer formulation of a chemical reaction and dissociating air is reduced to the incompressible Falkner-Skan equations by a combination...

(c)The standard molar enthalpy change for the reaction between calcium oxide and hydrochloric acid is -196.8 kJ mol-1.(i) Suggest three reasons why the calculated value in part (b) is different from this value.(3)Reason 1Reason 2Reason 3(ii) Using the standard enthalpy change of -196.8...
To find the entropy change (ΔS) for the process of melting ice (H₂O solid) to water (H₂O liquid), we can use the formula: ΔS=ΔHT where:-ΔH is the enthalpy change,- T is the temperature in Kelvin. Step 1: Identify the given values- The enthalpy change (ΔH) for th...
New Evidence of LiO2 Dismutation in Lithium–Air Battery Cathodes. ChemElectroChem 2016, 3(10): 1537–1540. A recent calculation by the group of Shao-Horn has shown that the greater Li+ solvation lowers the Li+/Li potential while greater O2– solvation increases the of O2/O2– potential.40...
