[ noun ] (chemistry) the state of matter distinguished from the solid and liquid states by: relatively low density and viscosity; relatively great expansion and contraction with changes in pressure and temperature; the ability to diffuse readily
Used in print (Raymond C. Binder et al., editors, Proceedings...)Gas injection through a porous anode ( transpiration cooling ) not_only feeds_back the energy transferred to the anode by the above mentioned processes , but also modifies the conditions in the arc itself . (Harry H. Hull, "The Normal Forces and Their Ther...)Note that though the ideal_gas itself contains no additional energy , the compressed gas does exert an increased pressure . (James A. Ibers et al., "Proton magnetic resonance...)Mass_spectrometric analysis of gases evolved upon heating to 410 ` C indicated nitrogen_oxides and water_vapor . For the low-temperature measurements the sample was cooled by a cold nitrogen gas flow method similar to that of Andrew and Eades . (Francis J. Johnston and John E. Willard, "The...)In the gas phase , with * * f of * * f and * * f of * * f , quantum yields of the order of * * f have been observed at 85 ` . Related terms |

[ noun ] (chemistry) a fluid in the gaseous state having neither independent shape nor volume and being able to expand indefinitely
Used in print (Raymond C. Binder et al., editors, Proceedings...)Experiments were made on an electric arc applying a porous graphite anode cooled by a transpiring gas ( Argon ) . The dependence of the arc voltage upon the mass flow velocity of the transpirating gas was investigated for various arc lengths and currents between 100 Amp and 200 Amp . The gas flow through a plasma generator will modify these conditions ; however , the anode is still the part receiving the largest heat flux . Feed_back of the energy transferred to the anode by applying gas transpiration through the anode . The transpiring gas ejected from the anode formed a jet directed axially towards the cathode below .
