Activity 1 1-19-11 Gasses

Gases
Far apart-cooling of balloon
Density different-Based on observations/molecular determines weight
Lots of movement-rather slow-bumping into one another
Naming of common gases

Ideal Gas Law
PV=nRT
P=Pressure
V=Volume
N=moles of gas
T=temperature
R=Gas constant
Balloon- increase the volume and the temperature is going up/direct relationship
If the pressure is decreased the balloon will increase in volume/ inverse relationship
If you add molecules to the balloon the volume will increase/direct relationship

PV=nRT           PV=R
nT    NT            nT
