Hello! I was playing around with a problem and while I was doing it I noticed a similarity between Cv*T=h by using Celcius and not Kelvin. So if I have a compressed liquid at say 50°C, looking up at a property table I find the hf to be 209.34 kJ/kg (the pressure is considered to be low). If you take the equation Cv*T, where Cv≈4.18 and T=50°C you get 209 kJ/kg. Doing this with kelvin instead gives a much larger number. My question is why is the relation here Celcius? Does it have something to do with the saturated water tables being Celcius dependent?
