QUESTION:

Explain melting and freezing using the kinetic theory of matter.

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. These attractive forces can be any of several types:

Covalent.
Hydrogen (polar).
Ionic.
Van der Waals.

The temperature of solid which melts and turned into liquid when heat is applied is called melting.

The temperature of a liquid which becomes a solid at normal atmosphereic pressure is called freezing .

A rocket moves upward from rest with an acceleration of 40 m/s2 for 5 seconds. It then runs out of fuel and continues to move up

Snezhnost [94]

Answer:

Maximum height of rocket = 2538.74 m

Explanation:

We have equation of motion s = ut + 0.5 at²

For first 5 seconds

s = 0 x 5 + 0.5 x 40 x 5² = 500 m

Now let us find out time after 5 seconds rocket move upward.

We have the equation of motion v = u + at

After 5 seconds velocity of rocket

v = 0 + 40 x 5 = 200 m/s

After 5 seconds the velocity reduces 9.8m/s per second due to gravity.

Time of flying after 5 seconds

$t=\frac{200}{9.81}=20.38s$

Distance traveled in this 20.38 s

s = 200 x 20.38 - 0.5 x 9.81 x 20.38² = 2038.74 m

Maximum height of rocket = 500 +2038.74 = 2538.74 m
