There Exists Another

Before we discuss about cosmos and elementary particles let me make you certain things clear. This is not a scientific journal that discusses results with proofs, mathematical equations and such other things.

And next this concept is not mine. This is an idea; perfectly to call rough idea proposed by my friend. He never ever written on this concept or gone through the depths of cosmos or element particles.

We may go on with Einstein, who states time never existed before universe actually existed and it is relative that time has considerably began with the universe.

If at all like many philosophers if you won’t agree with this we are left with another option: hawking universe which states that universe may not have any beginning or end. It existed always. This concept also discusses about imaginary time [real time refers to the one we are living or the one which is known about].

We will now speak on the basic lines; considering the electrons revolving around sun, solar system in turn revolving around galaxy centre and galaxies around centre of universe; we may conclude that there exists universes and baby universes.

You may now point upon the failure of Rutherford’s planetary model which explains the properties of atom in comparison to that of solar system.

Before you conclude to read this article, note that ‘laws of physics’ are not same to every particle and there isn’t any unified theory that relates all of them but still there is a relative relation between them.

One may relate physics to person’s different stages of life. He respires, feels hunger although but has different body functions as life goes on.

If at all the concept of hawking universe is true completely; the universe had undergone change and existed in one or the other form and so are stars, planets , neutrons, and electrons and any other tiny or cosmic particle.

Hence I conclude this article; with a view that there are multiple universes and nature relates each of the elements or stages in one or the other methods may be known or unknown to us.

EVAPORATION AND CONDENSATION












Evaporation and condensation in a closed vessel



The factors effecting evaporation are:
1. Surface area of the container
2. Temperature of the surrounding
3. Humidity
4. Pressure
Etc…….




Evaporation: this process is explained as follows:

• When the molecules on the surface are collided against each other, there will be transfer of energy between them. When one of the molecules gets sufficient energy it gets transferred into the phase that has predominantly higher entropy.

The rate of evaporation is defined as the number of molecules that are getting them converted into other phase per unit time. From this it can be understood that rate of evaporation depend on the temperature[which is the only cause for kinetic energy of the molecules] and the area[factor deciding the number of molecules :there by deciding number of collisions]

• Humidity only affects the equilibrium point that has to reach for the system to have minimum energy and maximum entropy.


The rate of evaporation to be constant in a closed vessel can also be explained by the fact that rate of reaction is directly proportional to number of fruitful collisions which is always constant.

Thus the graph between condensation & evaporation in closed vessel is:
the rate of condensation increases as the number of molecules
