The volume of a gas is 0.400 L when the pressure is 2.00 atm. At the same temperature, what is the pressure at which the volume of the gas is 2.0 L?
In this question , the gas is kept under the same temperature. Assuming the amount of gas is constant we can apply Boyles' law.
As per the Boyle' law equation;
2 atm x 0.400 L =
0.800 atm L = 2
dividing both the sides by 2 we get,
0.400 atm =
