Question 161606
The volume of a gas V held at a constant temperature in a closed container varies inversely with its pressure P. If the volume of a gas is 600 cubic centimeters (cm3) when the pressure is 150 millimeter of mercury (mm Hg), find the volume when the pressure is 200 mm Hg.
:
Using the first scenario find the constant (k)
{{{k/150}}} = 600 
k = 600 * 150
k = 90000
:
Find the volume when the pressure is 200
V = {{{k/P}}}
V = {{{90000/200}}}
V = 450 cu cm
