Ionization Chamber

The free-air chamber allows the entry of smoke particles to the sensitive volume and to change attenuation of alpha particles. If any smoke particles enter the free-air chamber, some of the ions will attach to the particles and not be available to carry the current in that chamber. An electronic circuit detects that a current difference has ...9.2 Relating Pressure, Volume, Amount, and Temperature ...For a constant volume and amount of air, the pressure and temperature are directly proportional, provided the temperature is in kelvin.
