Q20. A certain gas in a closed container at 0.001 atmospheres of pressure is irradiated with
ionizing radiation, causing on average one electron to be stripped off each atom. The ionizing
radiation also heats the gas from 20°C to 3000°C. The resulting ionized gas ("plasma") behaves
like an ideal gas. What is the pressure in the plasma?
a. 4.92'103 Pa
b. 3.04'105 Pa
O c. 1.23'103 Pa
d. 2.26'103 Pa
