Which of the following statements related to kinetic-molecular theory of gases is correct for an ideal gas?
A. Gas particles move in a zigzag pattern until they collide with something.
B. The pressure of a gas arises from the sum of the collisions of the particles with the walls of the container.
C. In a mixture of gases, attractive forces between particles cause the measured pressure to be lower than that expected for a pure gas.
D. When gas particles collide, they lose some of their kinetic energy, and will slow down over time.
E. Gases are composed of small particles with a small amount of space between them.
