Take two containers, each with volume 0.1 m3, containing ideal gases of monatomic He at T= 118 K and diatomic N2 at T = 257 K, respectively. Each gas is at pressure p= 106 Pa. A valve is opened allowing these two gases to mix. They are kept thermally isolated from the outside.
A charged particle is projected in a uniform electric field between two plates with initial velocity 5x10^3m/s at angle 40 degrees to the x-axis. Its charge is q= -1.0x10^-11 C and mass is m=3.0x10^-14 kg.
