A bicycle pump contains air at one atmosphere and 0°C. As the tire is pumped up, the volume of air decreases by 50% with each stroke. What is the new pressure of air (in atm) in the chamber after the first stroke, assuming no temperature change?
A) 2
B) 1
C) 0.5
D) 0.1
E) 3

According to Boyle's Law, pressure and volume are inversely proportional when temperature is constant. Halving the volume doubles the pressure, making it 2 atm.
