Answer to Question #183781 in General Chemistry for Keke

Question

Gases unit

1.Explain Boyle law terms of the kinetic Molecular theory and use details diagram and graphs to aid in explanation

2. There are certain situations where gases are non ideal 

a. Identity the two scenarios 

b. Using the kinetic Molecular theory choose one scenarios and explain what actually happens and why.

Answer 1

n Boyle's Law the temperature is helped constant, so the kinetic energy of the molecules is a constant. The pressure and the volume are inversely related in Boyle's Law.

What happens in Boyle's Law is that the molecules are forced more closely together. The more densely packed the gas molecules are the more often they will collide creating more pressure. So if the volume is less the number of collisions and pressure will be greater. If the volume is greater the number of collisions and pressure will be less. So volume and pressure are inversely related if the temperature and total kinetic energy is kept constant.

A real gas deviates most from an ideal gas at low temperatures and high pressures. Gases are most ideal at high temperature and low pressure. Nitrogen gas that has been cooled to 77 K has turned to a liquid and must be stored in a vacuum insulated container to prevent it from rapidly vaporizing.
