Kinetic Theory of Gases
1. This question has 4 part(s).
1.1. The kinetic theory of gasses is based upon a number of assumptions.
Place ticks (✓) next to the correct assumptions in Table 1.1.
Table 1.1
Possible statements of the kinetic theory of gases | Place a tick (✓) here |
The time of a collision is equal to the time between collisions | |
The molecules are mostly stationary but move upon collision with another molecule | |
Molecules of gas behave as identical, hard, perfectly elastic spheres | |
The volume of molecules is significant compared to the volume of the container | |
The time of a collision is negligible compared to the time between collisions | |
There are no forces of attraction or repulsion between the molecules | |
The molecules are in continuous random motion | |
The molecules all have mass, so are attracted towards each other | |
The volume of the molecules is negligible compared to the volume of the container |
