Question

question 1 10 pts 0.920 atm equals to: 0.920 mm hg 920 mm hg 699 mm hg 760 mm hg question 2 10 pts the pressure of a gas in a 15 - l container is 2.4 atm. if the volume of the container doubles, the pressure: does not change decreases to 1.2 atm increases to 4.8 atm increases to 30 atm

Explanation:

Step1: Recall pressure - unit conversion

1 atm = 760 mm Hg.

Step2: Convert 0.920 atm to mm Hg

$0.920\times760 = 699.2\approx699$ mm Hg.

Step3: Recall Boyle's Law for Question 2

Boyle's Law is $P_1V_1 = P_2V_2$. Initial $P_1 = 2.4$ atm, $V_1=15$ L. New $V_2 = 2V_1 = 30$ L.

Step4: Calculate new pressure

$P_2=\frac{P_1V_1}{V_2}=\frac{2.4\times15}{30}=1.2$ atm.

Answer:

Question 1: C. 699 mm Hg
Question 2: B. decreases to 1.2 atm
