what happens in a liquid when it begins boiling.
Ex. 3. Give detailed answers to the questions.
1. In what way docs vaporization procccd? 2. What is liquid-vapour
equilibrium? 3. How docs temperature influence the vapour pressure?
Ex. 4. Discuss the following topics:
1. The Vaporization Proccss.
2. The Phase Equilibrium.
3. Factors Influencing the Vapour Pressure.
