Homework Help: Chemistry

Posted by Mary on Friday, November 6, 2009 at 5:54pm.

Gas particles travel at speeds of up to 500 m/s. Why, then, does it take so long for gas molecules to travel the length of a room?

My answer would be that the molecules still have a weak attraction to each other and, in addition, the friction of the molecules surrounding the gas, which are in the atmosphere, impede the gaseous molecules' movement across the room. Is this correct?
