What if Lions Ruled the World?

No Ways.

AumSum will always rule the world.

Oh AumSum.

Firstly, if Lions ruled the world, Lions have massive beards.

People may now start growing long beards in order to impress the Lions.

Secondly, if Lions ruled the world, everyone will now have to learn how to roar like a Lion.

Thirdly, if Lions ruled the world, salons may be busy grooming Lions, we may have to start cutting our own hair.

Fourthly, if Lions ruled the world, Lions are extremely fit and muscular.

Everyone may try to build their muscles in order to impress the Lions.

Fifthly, if Lions ruled the world, keeping Lions entertained will not be an easy task.

Entertainers may rule for a different planet.

Lastly, if Lions ruled the world, dentists may start fainting after having a look at Lion's sharp teeth.

Topic Gravitational Force.

Why do you weigh less on the moon?

Hey.

What are you doing?

It is not possible.

You cannot fly on earth.

Please listen.

Look.

I had warned you.

Now, why don't you try the same activity on the moon?

There you will weigh much less and thus, you can fly short distances.

What is this?

See.

I was correct.

Do you know why you weighed less on the moon?

To understand this, we need to first learn about weight.

No.

Not those weights.

Weight is the force with which an object is pulled towards the center of the earth or any other celestial body.

This force is called the gravitational force.

Greater the gravitational force exerted by the celestial body.

More will be the weight of an object present on it.

So, does this mean that the moon exerts less gravitational force than the earth?

Bingo.

You are right.

But do you know why?

This is because gravitational force is directly proportional to the mass of an object.

Greater the mass.

Greater will be the gravitational force exerted by it and thus, more will be our weight.

As the moon has lesser mass than the earth.

It has a weaker gravitational pull and hence, we weigh less on the moon.

Topic.

Sublimation.

Why do mothballs disappear over time?

Wow.

You have a nice collection of clothes.

But have you kept mothballs to protect them?

Yes.

I had kept them a few months back below these clothes.

Hey.

Where did the mothballs go?

I had placed them right here.

Did you steal them?

No.

I haven't stolen anything.

Mothballs disappear over time.

Do you know why?

It is because they are very expensive.

Because of a process called sublimation.

During sublimation, a solid on heating converts directly into vapor.

Without passing through the intermediate liquid state.

Don't lie.

How is that even possible?

See.

I also hid a burger here many days ago.

It did not disappear.

Gross.

Just throw that burger in the dustbin.

Not all substances sublimate.

Mothballs are made up of naphthalene.

Naphthalene has very weak intermolecular forces.

Because of these weak forces.

The mothball which is made up of naphthalene sublimates.

That is, it changes its state from solid to vapor.

Now, this vapor is either absorbed by the fabric.

Or it escapes into the atmosphere causing the mothballs to disappear over time.
