(1) alpha is your answer. The alpha particle is a Helium nucleus, with two protons and two neutrons. Therefore its larger than the positron or the neutron (because positrons have around the same mass as the proton, being its anti-particle). The beta particle is just the electron, in which the proton is way more massive than the electron.

A container of oxygen with a fixed volume has a pressure of 13.0 atm at a temperature of 20 °C. What will the pressure of the ox
Norma-Jean [14]

Given:

P1 = 13.0 atm

T1 = 20 °C

T2 = 102 °C

Required:

P2 of oxygen

Solution:

At constant volume, we can apply Gay-Lussac’s law of pressure and temperature relationship

P1/T1=P2/T2

(13.0 atm) / (20 °C) = P2 / (102 °C)

P2 = 66.3 atm

The answer is not in the choices given.
