Boyles Law
Describes how the pressure of a gas tends to increase as the volume of the container decreases
Boyles Law holds true only if the number of _____ and the _____ are both constant
molecules, temperature
200N/m2/1000K=P/ 400 K
200N/m2(400K)/1000K=P2

decreases
The gas is an aerosol can is at a pressure of 3.00atm at 25C. The can warns not to allow the temperature to get above 52C. What would the pressure of the can be at 52C?
P2= (3.00)(273+52)/(273+25)= 3.25 atm
