When perfume or cologne is sprayed into the air, it turns into a gas and its particles mix with other air particles that quickly move around the room. This is because gas is the least dense of the three states of matter. It moves quickly into any space or volume because it has the least density. This is called diffusion, when molecules or particles move from areas with high concentration to low concentration areas.
D! the molecules of the warmer water would have a higher average kinetic energy :)
Proton is a positively charged particle
D= mass over volume
So, density equals 9.0g divided by 45ml.
SO, D=.25 g/ml
I'm not 100% sure this is correct, though. Best if luck. ♡
