Use of periodic-heating method for measurement of thermal activity coefficient of gases

  • 22 Accesses


A method of increasing the sensitivity of the circuit for measuring the thermal activity coefficient of gases by the periodic-heating method is proposed. The thermal activity of argon, carbon dioxide, and air at 1300°K was measured.
