Answer:
The new pressure is 40 atm
Explanation:
Step 1: Data given
Volume of the gas = 20.0 L
Pressure of the gas = 10.0 atm
The volume decreases to 5.0 L
Step 2: Calculate the new pressure
P1*V1 = P2*V2
⇒with P1 = the initial pressure of the gas = 10.0 atm
⇒with V1 = the initial volume of the gas = 20.0 L
⇒with P2 = the new pressure = TO BE DETERMINED
⇒with V2 = the decreased volume = 5.0 L
10.0 atm * 20.0 L = P2 * 5.0 L
P2 = 200 / 5.0
P2 = 40 atm
Since the volume is 4x smaller, the pressure is 4x more
The new pressure is 40 atm
