30cm(^3) of oxygen at 10 atmospheres pressure is placed in a 20 cm(^3) container. Calculate the new pressure if temperature is kept constant?
-
A.
6.7 atm -
B.
15.0 atm -
C.
60.0 atm -
D.
66. 0 atm
Correct Answer: Option B
Explanation
P(_1)V(_1) = P(_2)V(_2) (where T is kept constant)
30 x 10 = P(_2) x 20
P(_2) = (frac{30 times 10}{20})
= 15.0 atm
