WebThe Joule-Thomson coefficient for CO 2 at 2.00 MPa is 0.0150°C/kPa. Carbon dioxide initially at 20.0°C is throttled from 2.00 MPa to atmospheric pressure. Determine the … Web5 jun. 2024 · This is a funny one to answer: hydrogen and helium are the only two gases that have a negative Joule-Thomson coefficient, meaning that they warm up when expanding instead of cooling down like the rest of the gases we know.
WebIn a Joule–Thomson expansion the enthalpy remains constant. The enthalpy, H, is defined as H = U + P V where U is internal energy, P is pressure, and V is volume. Under the conditions of a Joule–Thomson expansion, the change in P V represents the work done by the fluid (see the proof below).
