Enthalpy used in a sentence

Enthalpy in a sentence as a noun

Yeah and i'm still trying to understand the enthalpy curve of the two systems but at the same given temp it's way further along the X-axis for 33'C[0][1]. 33'C is a pretty common for a huge chunk of the earth.

I simply calculated the enthalpy of 3 liters of the mixture. The energy due to the pressure buildup is negligible.

It's true that we are also open systems in meaningful ways and can be farmers of enthalpy inside our bodies. To some extent that's exactly what life is--enthalpy farming equipment.

It's multiple GJ/tonne just to reverse atmospheric entropy and get the CO2 where you want it, and that's before you have to climb backwards up combustion's enthalpy cliff to turn it back into usable fuel. But the capture cost is a rounding error, even at 1GJ/tonne.

* the concept of heat is of course horrendous from a scientific point of view and we do use things like enthalpy and entropy in modern thermodynamics. But there’s a reason why heat is used in vulgarisation and introductions.

There are lots of enthalpy recovery systems on the market, some that can recover >75% of the 'waste' energy, though mostly aimed at larger customers. You need to do a cost-benefit analysis to see if it makes sense to spend the upfront cost.

You're talking about a small decimal point variation in heat of vaporization aka enthalpy of vaporization. You are correct it does in fact vary by temp, but as a percentage, less than my vast rounding errors.

To really understand what's going on, you need high enthalpy, high pressure, high Mach number flow for a reasonably long period of time. Experimental scaling is only so helpful depending on what you're trying to investigate.

Even without pulling up the enthalpy of combustion of the molecules, I’d still wager that the 3-H’s combing with O2’s will produce more than the balance of re-capturing the C’s.

The enthalpy differences between phases are so small that changes of only a few meV per proton can make a noticeable difference to the phase diagram so that's some physics. They seem to end up using DMC for the static lattice and DFT for the vibrational corrections on top of that.

Energy is never free, so apart from enthalpy beating entropy locally, tech that flows downhill usually wins with developers and publishers. Game devs/pubs porting their C++ catalogs to JS via Emscripten is an example of "flowing downhill".

The linked document shows humid air having an enthalpy of 75kJ/kg at 25C, so that explains why humidity increases perceived heat and increases the energy needed to heat up humid air, but the heat itself is coming from car engines, and the humidity from tailpipes. On the whole, i don't find underground carparks notably humid, but they are warm.

What you are describing is how higher pressures allow you to add energy to the water while it remains liquid, and how if you add enough energy it will overcome the enthalpy of vaporization and cause it to convert to steam as the pressure is reduced.

You see words like entropy and enthalpy thrown around, and then some American mathematicians get involved, and suddenly there's also negtropy and fractional bits, and nothing makes any kind of sense anymore - temperatures going below absolute zero, the "nothing actually moves anymore" point, leading to negative temperatures where heat flows from colder to hotter... ...
