Sentences with phrase «enthalpy when»
The public use of temperature rather than enthalpy when choosing a metric to explain climate change that has been exposed as problematic with the skeptics using the same methodology as the IPCC communicators to claim the warming has stopped, or that we are actually cooling.

In the classical view (bold line), metastable clusters form and nucleation occurs when the critical nucleation enthalpy ΔG * is overcome.
When the two airstreams also exchange moisture, you have an energy (or enthalpy) recovery ventilator (ERV).
Climate Alchemy and probably most scientists not taught chemical thermodynamics don't realise that the main heat transfer term in the oceans is the partial molar enthalpy transferred when the fresh, cold water sinking from melting ice in the Antarctic and Arctic summers is made more saline when it mixes with the warmer, more saline surface water for which solar energy has partially unmixed the ions.
What is the compelling reason to introduce enthalpy, when we don't need it?
A polytropic process proceeds with an apparent constant heat capacity Ch and d' Q = Ch dT = Cp dT — R T dP / P When going from T0 to T the changes of the internal energy and of the enthalpy are Cv (T - T0) and Cp (T - T0) while the heat transferred to the gas is Ch (T - T0); it is zero for an adiabatic and RT ln (P / P0) for a constant temperature process.
In my mind that will occur when we regularly measure the enthalpy of the environment and lead with that, not just the temperature.
Steve — I have stated multiple times that the climatologists are all gathered under the lamppost as its light there — using atmospheric temperature when they should be measuring atmospheric heat content in kilojoules per kilogram taking account of the enthalpy.
«An alternative description is to view the enthalpy of condensation as the heat which must be released to the surroundings to compensate for the drop in entropy when a gas condenses to a liquid.»
