The thermodynamics is the branch of physics that deals with the energy transfer due to heat, change in enthalpy of the substance, the change in entropy, heat engine etc.Answer and Explanation: The specific heat can be determined by with the help of heat energy trnasfer formula. The formula ...
How to find melting point with specific heat? Specific heat and melting point: Specific heat: means the amount of heat that could raise up the temperature of 1 kg of substance by 1 degree C. Melting point: is the point where the substance changes from one phase to another, (solid to li...
Hence, I need to introduce sensible (but not necessarily precise) thermodynamic properties for the vapour phase, as well, so that thesimulationeffectively remains inpure liquid. I have all theliquidlaws needed, for the following properties: specific enthalpyhl(p,T)=(34.5+0.235×(T−273.15))×...
From the definition of , it is possible to obtain the specific volume of the gas. (Using SI units whenever units don't cancel) Lastly, knowing the tank's volume is we can find the actual mass. I'm not sure if it's my first or second time in my life doing these calculations but ...
Cp: Specific heat of pipe material in kj/kgoC hfg: Enthalpy of evaporation or saturated enthalpy at operating pressure in kj/kg t: Time of warming-up in minutes Note:Suppose if the warm-up/heating time of the system is increased to 12 minutes from 6 minutes, then the initial flow rate...
Find the required approach in the manufacturers installation instructions, which will be specific to the condenser you are servicing. Measure the outdoor air temperature entering the condenser from top to bottom of the coil outside of line of site of the sun and obtain an average condenser ...
The enthalpy of the output flow is known since you know the temperature and pressure of the saturated mix at any moment so you can find it in tables (notice that it'll change as time passes). Lastly, the energy in the control volume will be only the internal energy of the gas and li...

What's the difference between heat capacity and enthalpy change? What is the specific heat capacity of substance X when 34.80 g of X is heated from a starting temperature of 20.5^oC to 40.9^oC by 2.54 kJ of energy? Calculate how much heat 32.0 g of water absorbs when it is heated from...
What is the formula for specific heat capacity? Calculate the mass in grams of carbon needed to produce 160 g of CO_2 in burning: C + O_2 to CO_2 Suppose that polluted air has carbon monoxide (CO) levels of 15.0 ppm. An average human inhales about 0.50 L of air per breath and ...
