In 1.0s, 5.0x10^23 nitrogen molecules strike an area of8.0cm^2 at a speed of 300m/s. What is the pressure? (mass of one nitrogen molecule = 4.68x10^-26 kg.) I believe I should use 1/2mv ^2 for the solution but the answer I keep getting is nowhere near correct. Can someone help with this?
The energy needed to ionize an atom is known as ionization energy. It is the energy needed to make the electron jump from the present orbit to the infinite orbit.
