Number 4, please. The question is "A gas has a temperature of 14°C and a volume of 4.50L. If the temperature is raised to 298°C and the pressure is not changed, what is the new volume of the gas?"

But, what is the original pressure??

Answer :

 the new volume is 8.95 L 
you can use the V1P1/T1=V2P2/T2
you know the pressures are the same
so the ratio of volume divided by temperature should be the same
so 
4.5L/287K(kelvins you add 273 to celsius)=xL(unknown volume)/571K(the new temp)
this will give you the new volume!
