Steam at $100\,^{\circ}\text{C}$ changes into water at $100\,^{\circ}\text{C}$. What happens to the average distance between the water molecules, and what happens to their average speed?
- Aseparation decreases; average speed decreases
- Bseparation decreases; average speed remains the same
- Cseparation increases; average speed decreases
- Dseparation increases; average speed remains the same
