6. The freezing point of glycerol is 17.8°C and its boiling point is 290°С. Find its melting poman
condensation point.
G. Answer the following in detail.
1. On the basis of the kinetic theory of matter, explain why
a. solids have a fixed shape and a fixed volume.
b. liquids have a fixed volume but not a fixed shape.
C. gases have neither a fixed volume nor a fixed shape.
2. State the main postulates of the kinetic theory of matter.
3. Explain conduction of heat in solids on the basis of the kinetic theory of matter.
4. Demonstrate the process of boiling with the help of an activity.​

Answer 1

Answer:

As a liquid is cooled its molecules lose kinetic energy and their motion slows. When they've slowed to where intermolecular attractive forces exceed the collisional forces from random motion, then a phase transition from liquid to solid state takes place and the material freezes.May 7, 2018
