Answer:
the protons will jump to the negatively charged object making it negatively charged
<u>Answer:</u> The quantity relating pressure and volume is
and the size of the tank must be 
<u>Explanation:</u>
To calculate the new volume, we use the equation given by Boyle's law. This law states that pressure is inversely proportional to the volume of the gas at constant temperature.
Mathematically,

Or,

The equation given by this law is:

where,
are initial pressure and volume.
are final pressure and volume.
We are given:

Putting values in above equation, we get:

Hence, the size of the tank must be
