Answer:
Volume will increase by factor 2
So option (A) will be correct answer
Explanation:
Let initially the volume is V pressure is P and temperature is T
According to ideal gas equation
, here n is number of moles and R is gas constant
So
....................eqn 1
Now pressure is doubled and temperature is quadrupled
So new volume
........eqn 2
Now comparing eqn 1 nad eqn 2

So volume will increase by factor 2
So option (A) will be correct answer
Answer: option d: The nucleus of Atom Q is more stable than the nucleus of Atom P.
Explanation:
Atom P is radioactive and disintegrates, it emits beta particles (high speed electrons or positrons) because it is not stable. On disintegration, it forms a stable Atom Q which is non-radioactive and thus it does not disintegrates further.
Thus, the correct option is only d. The nucleus of Atom Q is more stable than the nucleus of Atom P.
