Q:1-Suppose that a gas originally at standard temperature and pressure undergoes a change in which its pressure is quadrupled while its temperature is cut in half. What change in volume does the gas experience during this process?
Mark one answer:
Increase by a factor of 8
Decrease by a factor of 8
Decrease by a factor of 2
Increase by a factor of 2
The volume of the gas will not change

Q:7-A proton traveling at 1 * 10⁷m/s in a horizontal plane passes through an opening into a mass spectrometer with a uniform 3T magnetic field directed upward. The particle then moves in a circular path through 180º and crashes into the wall of the spectrometer adjacent to the entrance opening. How far down from the entrance is the proton when it crashes into the wall?
The proton’s mass is 1.67 * 10^-27kg and its electric charge is 1.6 * 10^-19C.
