With molar quantity and temperature held constant,by what factor does the pressure of an ideal gas change when the volume is four times bigger?
A) 16
B) 4
C) 1/4
D) 1/16

Question

Quizplus · Accepted Answer

According to Boyle's Law, the pressure of an ideal gas is inversely proportional to its volume at constant temperature and molar quantity. Therefore, if the volume increases four times (i.e., becomes four times bigger), the pressure will decrease by a factor of four, or 1/4 of the original pressure. Therefore, the correct answer is C) 1/4.
