##### 19. Question

Category: T20. Laughing gas, N

_{2}O, and tear gas, NH_{3}, are released at the same time at an equal distance away from you. Particles of laughing gas and tear gas move by simple diffusion and each molecule has the same kinetic energy. The room is perfectly sealed with no prevalent air current. Would you laugh or cry first?

Kinetic energy = ½mn
