A sample of gas has a volume of 3.50 L and a temperature of 298 K. What would be the volume of the same gas sample if the temperature is decreased to 285 K at a constant pressure?

Initial Conditions:
Volume=v1= 3.5 L
Temperature= T1 =298K
 
Final Conditions:
Temperature= T2= 285K
Volume= v2= ?

Use the general gas equation;
                                        P1*v1/T1 = P2*v2/T2

Note:
Pressure is constant
so the equation become,
                                           v1/T1 = v2/T2
                                          3.5/298 = v2/285
                                              v2 = 3.347 L
