Problema Solution
When the temperature stays the same, the volume of a gas is inversely proportional to the pressure of the gas. If a balloon is filled with 105 cubic inches of a gas at a pressure of 14 pounds per square inch, find the new pressure of the gas if the volume is decreased to 15 cubic inches.
Answer provided by our tutors
v = k/p
105 = k/14
105*14 = k
1470 = k
v = 1470/p
15 = 1470/p
15p = 1470
p = 98
pressure is 98 pounds per square inch
