One liter of a gas is in a sealed chamber containing a moveable piston. if the piston is moved so that the volume of the gas is compressed to a volume of one-half liter, what will happen to the pressure on the gas? (assume the temperature is constant and no gas particles are lost.)

a)the pressure will be twice the original value.
b)the pressure will be half of the original value.
c)it would be impossible to move the piston since gases are not compressible.
d)the pressure will remain the same.

a) The pressure wiil be twice the original value

Explanation:

Pressure in inversely proportional to volume, that means; when one value decreases at the same rate that the other increases, if the temperature and amount of gas remain unchanged within a closed system. The above derived from the same definition of pressure.  The pressure is defined as the crashes and frequency of the same agains surface of objects, if certain amount of gas is  contained in a recipent, It will crash more times if the volume is minor. The Boyle´s law  express this mathematically.
