True or falseTrue or false
• According to the kinetic-molecular theory, particles of a gas collide?
• According to the kinetic-molecular theory, particles gain and lose energy after an elastic collision?
• According to the kinetic-molecular theory, particles of a gas attract each other?
• According to the kinetic-molecular theory, particles of a gas repel each other?
• According to the kinetic-molecular theory, particles of a gas collide?
• According to the kinetic-molecular theory, particles gain and lose energy after an elastic collision?
• According to the kinetic-molecular theory, particles of a gas attract each other?
• According to the kinetic-molecular theory, particles of a gas repel each other?
Gas particles neither attract nor repel each other, but they do collide in a elastic collision. Elastic Collisions result in NO net loss of energy.
