Introduction

There are many things Absolute Zero can do. Based on what we found out, it can freeze people and preserve them although it's many more uses are still unknown.

Absolute Zero is known to man as the lowest temperature possible according to scientists but nobody has ever reached that temperature before. At the very most, the lowest temperature ever reached is 450pK(0.45nanoK) Link HERE. Nobody can achieve absolute zero or somewhere close to it, since it would be IMPOSSIBLE to reach temperatures like that. We may use different methods of cooling like laser cooling and evaporative cooling to get close there Link HERE. We will be using liquid nitrogen since it is already only 77K or less and we may still further lower the temperature. I found out why it is impossible to reach Absolute 0. The main reason is that we need to abstract infinite energy from the particles. It is just like how particles cannot move at the speed of light because infinite energy is needed to make it move at that speed. Also, reaching that temperature will break the 3rd law of thermodynamics.

The 3rd law of thermodynamics, based on research, is regarding the properties of systems in equilibrium at absolute zero temperature where The entropy of a perfect crystal at absolute zero is exactly equal to zero.

It is thought that when particles cannot move, it means that there is NO volume. So, when a balloon is in absolute zero condition, the gas in the balloon is of no volume. This means that the lower the temperature of the particles, the lower its volume. We want to reach temperatures around it we have to use something called a cooling bath. A cooling bath is used to cool matter to temperatures never reached before and stay that. Since we will be doing something like use a cooling bath, we need cooling agents like liquid nitrogen (-196 oC) or its equivalent to cool particles to find out whether or not the particles actually reach there.

The only way to find out the speed of particles is to use brownian motion which is to use watch the particles under a microscope where it gets bombarded by air particles.Research shows that the lower the temperature of the particles, the slower it will move and at absolute zero, the particles will not move at all.

Another factor that affects the speed of particles is pressure. The lower the pressure, the lower the boiling and melting point and vice versa. Meaning, if we use liquid nitrogen at normal earth pressure compared to mount everest pressure, the liquid nitrogen is at a lower temperature at mt everest than normal circumstances. I also found out through research is that the pressure changes because the amount of air increases or decreases. So, for our project, we will put our set-ups in a pressure chamber and increase the atm for 2 of the setups, decrease the atm in another 2 and the rest of them, instead of increasing the atm.

*atm: atmospheric pressure.
