Gases
- Properties
- They no shape and volume
- They diffuse readily, 2 gases will mix if combined
- They can be compressed easily
- They have lower densities than liquid
- KMT
- Gas consists of tiny molecules
- The distance of molecules is larger than the molecules
- Gas molecule has no attraction from one another
- They move in straight lines, in all directions
- Collisions are elastic
- The average kinetic energy for molecules is same for all gases at the same temperature and its value is directly proprtional to the kelvin temp
- Gas Laws
- Boyle's Law
- P1V1=P2V2
- Charles Law
- V1/T1=V2/T2
- Gay-Lussacs Law
- P1/T1=P2/T2
- Combined Gas Law
- P1V1/T1=P2V2/T2
- Ideal Gas Law
- PV=nRT
