Entropy is one way to measure energy and is given in joules per Kelvin. If the change in entropy is positive, energy has entered the system. If the change in entropy is negative, energy has been given off. By calculating the change in entropy, you can determine how much energy a given ...
How to Calculate Entropy In anisothermal process, the change in entropy (delta-S) is the change in heat (Q) divided by theabsolute temperature(T): delta-S=Q/T In any reversible thermodynamic process, it can be represented in calculus as the integral from a process's initial state to its...
Calculate the change in entropy of half a kilogram of water at 0 degree C when it reaches its point of boiling. Consider that the process is carried out at sea level and that the thermal capacity specific value of water in its l...

How to calculate the energy change in the reaction N_2(g) + 3H_2(g) rightarrow 2NH_3(g)? What is the relationship between a compound's stability and its enthalpy of formation? How to measure energy What's the difference between heat of reaction and heat of formation?
I have used two methods to calculate entropy generation. First the Bejan correlation (((Wall Heat Flux[W/m^2])^2*3.142*(D[m])^2)/(Thermal Conductivity[W m^-1 K^-1]*(Average T)^2*Average Nu))+((32*(Average MFR)^3*Average FFF)/(3.142^2*(Density[kg/m^3])^2*Average T*(...
The equation to calculate density is represented with the formula density = mass / volume. To determine the density of a solid that has regular side lengths, it is first needed to calculate the volume of the solid using the equation volume = length x width x height. Once the volume is ...
Answer to: Explain, both in mathematical terms and in plain English, how changes in entropy and potential energy determine whether or not a...
How to calculate enthalpy change Enthalpy Change:Enthalpy change is a measure of the amount of energy released or absorbed during a chemical reaction. A negative enthalpy change indicates that heat was released (known as an exothermic reaction), while a positive enthalpy change indicates that heat ...
Re: How do I calculate enthalpy and entropy of this really complicated problem? «Reply #15 on:October 23, 2013, 02:36:30 PM » 8.31446 J/mol K. You can convert to kJ/mol K, but it's not 0.0831446; try 0.00831446. Looks like you need to start being a lot more careful with ...
