Alpha particle is the nuclear decay emission that has the weakest penetrating power. The correct option among all the options that are given in the question is the first option or option "1". Gamma is a type of radiation and so can be negated as a particle. Alpha particles have the largest radiation and so the weakest penetrating power.
Explanation:
C. Nobel gas are very stable because in their valance shell maximum number of electrons are present
The pressure on the inside of the other side of the bottle is; 130kPa and this is by virtue of Pascal's Principle.
<h3>Pressure and Pascal's Principle</h3>
According to Pascal’s principle, otherwise called Pascal’s law, in fluid (gas or liquid) mechanics, the statement goes thus, In a fluid at rest in a closed container, a pressure change in one part is transmitted without loss to every portion of the fluid and to the walls of the container in which the fluid is contained.
On this note, it follows that the pressure is transmitted to the walls of the bottle.

I would say that the density increases because the distance between the molecules decreases, and therefore becomes smaller, and vice versa the density increases, and that is a physical change not a chemical change.
