At a temperature of 500 kelvins, 6 liters of an ideal gas had a pressure of 300 newtons

per square meter. If the temperature was reduced to 250 kelvins, and the volume raised
to 9 liters, what was the resulting pressure ?
(A) 100 newtons/m^2
(B) 150 newtons/m^2
(C) 450 newtons/m^2
(D) 900 newtons/m^2
(E) none of these

Answer:

(A) 100 newtons/m^2

Step-by-step explanation:

Hello,

In this case, the equation defining such changes is:


P_1V_1T_2=P_2V_2T_1

Thus, the unknown is the pressure at the second state, which is found as shown below:


P_2=(P_1V_1T_2)/(V_2T_1)=(300Pa*6L*250K)/(9L*500K) \\P_2=100Pa=100(N)/(m^2)

Therefore, the answer is (A).

Best regards.
