Intro to Gas Laws Flashcards
1
Q
three major assumptions about the particles in a gas
A
- Their particles move in a straight line until they collide with other particles or the walls of their container.
- The motion of the particles is constant and random.
- There are no attractive or repulsive forces among the particles.
