Gas molecules can easily be compressed  because ___________. 

• gas molecules are soft
• gas molecules are far apart
• gas molecules follow the shape of the container

The kinetic theory states

• Particles won't move if you don't apply energy to it.

• Particles only move in liquids and gases.

• Particles are always in motion.

• At the same temperature the object that has the most mass heats quicker.

If you spray air freshener on side of the room, why is there a delay for the smell to reach the other side of the room? 


• Attractive forces between air and air freshener particles
• Not enough air freshener particles
• Because the particles like where they are at
• Collisions between air and air freshener particles
