A $1\text{ cm}^3$ portion of substance X is obtained; this is sample 1. X is then changed into another physical state, and a $1\text{ cm}^3$ portion is obtained. This is sample 2. Sample 2 has a greater number of particles in the $1\text{ cm}^3$ than sample 1. Which process led to this increase in the number of particles in $1\text{ cm}^3$?
- Aboiling of liquid X
- Bcondensation of gaseous X
- Cevaporation of liquid X
- Dsublimation of solid X
