A $1\,\text{cm}^3$ portion of substance X is collected. This is sample 1. X is then changed into another physical state, and a $1\,\text{cm}^3$ portion is collected. 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 rise 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
