Under these conditions the rate of increase of the current with the distance between the plates was a maximum. Helium remains in liquid form at absolute zero, at standard pressure. Electronaffinity, physical states, electrical conductivity and many more. Helium is also highly affected by the magnetic field and interacts with Earth’s magnetosphere to from aurora. Compare Helium vs Copper of the Periodic Table on all their Facts, Electronic. The plasma state of helium has high electrical conductivity. In addition, combined ordinary, pressure, and thermal diffusion coefficients are given for the mixtures. There is a considerable difference between the two states of helium. The thermal conductivity of helium is five times higher than the thermal conductivity of. The values of the ratio X/p were, 50 in pure helium, 200 in pure argon and 15 in the mixture. The equation of state of fluid hydrogen, helium, and their mixtures is determined within fluid variational theory. Abstract: Calculated values of the viscosity, thermal conductivity, and electrical conductivity of helium, and mixtures of argon and helium, at high temperatures are presented. Helium has a relatively high thermal conductivity of 0.1513 W/(mK). The three curves give the currents in pure helium, in pure argon and in helium containing 0.025 per cent of argon. Im pretty sure helium is not eletrically conductive since its a noble gas, dunno about in liquid form. 1, and the potential differences between the plates by the abscissæ. The photo-electric currents obtained with a constant force between parallel plates at different distances apart are represented by the ordinates of the curves, Fig. In gases, the electrical conductivity in uniform fields between parallel plates depends upon the ratio X/p, where X is the electrical intensity in volts per centimetre, and p is the pres sure in millimetres of mercury, and is a maximum for a certain value of X/p depending upon the nature of the gas. For example, the electrical conductivity of pure helium is greatly improved by the addition of 0.01 per cent of pure argon. IT is well known that the electrical conductivity of certain gases may be greatly increased by the addition of very small quantities of other gases. The main application of ultralow temperature is in the development of the superconductivity state, in which the resistance to the electricity flux is almost.
