As a bird soars high into the sky.the number of particles or air __ decreases stays the same increases Question 16 True or false, When the concentrations of two gases in a container are equal, diffusion stops. True False 0.25

## Step 1:<br />The first question is about the number of particles of air as a bird soars high into the sky. The number of particles of air doesn't change with the altitude. The volume of air particles expands with the increase in altitude, but the number of particles remains the same.<br /><br />## Step 2:<br /> question is or false question about diffusionusion is which an area of high concentration to an area concentration. The statement in the question suggests that when the concentrations of two gases in a container are equal, diffusion stops. This is false because even when the concentrations are equal, molecules continue to move back and forth between the two areas, maintaining a state of dynamic equilibrium.
