A gas contained in a 3 mL container at a temperature of 340 K has a pressure of 1.5 atm. If the temperature decreases to 325 K, what is the resulting pressure?
A) 165,750.0 atm
B) 1.6 atm
C) 170.0 atm
D) 1.4 atm

Using the ideal gas law and assuming the volume and amount of gas remain constant, the pressure is directly proportional to the temperature. Therefore, P1/T1 = P2/T2. Solving for P2 gives P2 = P1 * (T2/T1) = 1.5 atm * (325 K / 340 K) = 1.4 atm.
