dissolving is like when something forms.

lapo4ka [179]3 years ago
4 0

Explanation:

Like dissolves like means polar solvents dissolve polar molecules whereas non-polar solvents dissolve non-polar molecules.

For example, water (H_{2}O) is a polar solvent and it is able to dissolve NaCl (sodium chloride) because NaCl is a polar molecule.

Whereas benzene is a non-polar molecule and it is able to dissolve in CCl_{4} (carbon tetrachloride) solvent which is a non-polar solvent.

What are the two types of collisions? What is the difference between them? Types: a. Types: b. Compare and contrast the two type
mr_godi [17]

Answer:

The two types of collisions are :

Type a)

<u>Elastic collision</u>

Type b)

<u>Inelastic collision</u>

Explanation:

Collision : It is the event when two bodies collide with each other for small period of time.

During collision , the bodies exert force to each other.

Example :

When boxer hits with punches .

When bat hits the ball in cricket match.

So, collision is short duration interaction of two objects. When the objects collides , there is  change in their velocity.

All collision follow law of conservation of momentum . Their type is decided by , whether they follow conservation of energy also.

<u>Compare and contrast the two types</u>

a) Elastic collision : Those collision in which no loss or gain of kinetic energy will occur. They follow conservation of kinetic energy. Example : ideal gaseous molecule

b) Inelastic collision : Those collision in which Change in kinetic energy will occur. They do not follow conservation of kinetic energy.Almost all conservation are inelastic.

Here Kinetic energy get converted into other form of energy.
