Investigating the strength of electrolytic solutions essay

Of all the endless variety of phenomena which nature presents to our senses, there is none that fills our minds with greater wonder than that inconceivably complex movement which, in its entirety, we designate as human life; Its mysterious origin is veiled in the forever impenetrable mist of the past, its character is rendered incomprehensible by its infinite intricacy, and its destination is hidden in the unfathomable depths of the future. Whence does it come?

Anoxia will hit the crew when the atmospheric pressure drops to what pressure? From Living In Space by G. Artwork by Rick Sternbach. Low pressure is attractive; since it uses less mass and the atmosphere will escape more slowly through a meteor hole. Unfortunately the required higher oxygen level make living in such an environment as hazardous as chain-smoking inside a napalm factory.

NASA found that out the hard way in the Apollo 1 tragedy. Since then NASA always uses high pressure, they use low pressure in space suits only because they cannot avoid it.

This does raise a new problem. There is a chance that the high-oxygen atmosphere will allow a meteor to ignite a fire inside the suit. There are other problems as well, the impossibility of air-cooling electronic components and the risk of long-term health problems being two. Setting up the optimal breathable atmosphere is complicated.

A more annoying than serious problem with low pressure atmospheres is the fact that they preclude hot beverages and soups. It is impossible to heat water to a temperature higher than the local boiling point.

And the lower the pressure, the lower the boiling point. You may have seen references to this in the directions on certain packaged foods, the "high altitude" directions.

The temperature can be increased if one uses a pressure cooker, but safety inspectors might ask if it is worth having a potentially explosive device onboard a spacecraft just so you can have hot coffee. Human-breathable mixtures of oxygen and nitrogen as a function of barometric pressure the blue area.

Below inspired partical pressure pO2 60 mm Hg you suffer hypoxiaabove pO2 mm Hg you suffer oxygen toxicityabove pN2 mm Hg nitrogen narcosis From Habitable Planets for Manmodifed by me. It occurs when a person has been breathing an atmosphere containing inert gases generally nitrogen or helium and they move into an environment with lower pressure.

This is commonly when they put on a soft space suit or the room suffers an explosive decompression. It has all sorts of nasty effects, ranging from joint pain and rashes to paralysis and death.

The large joints can suffer deep pain from mild to excruciating. The brain can have sudden mood or behavior changes, confusion, memory loss, hallucinations, seizures, and unconsciousness. The legs can become paralyzed. Headache, fatigue, malaise, loss of balance, vertigo, dizziness, nausea, vomiting, hearing loss, shortness of breath, and urinary or fecal incontinence:The physical strength of a wave.

This is usually measured from peak (top) to valley (bottom) on a graph of the wave. The measure of the physical strength of the sound wave; it is defined in units of sound pressure or energy.

Nov 04,  · Electrochemistry is a branch of chemistry that studies chemical reactions which take place in a solution at the interface of an electron conductor (a metal or a semiconductor) and an ionic conductor (the electrolyte), and which involve electron transfer between the electrode and the electrolyte or species in solution.

Table 1 above shows the raw data of experiment I did to test the strength different electrolytic solutions. Moreover, this data table shows that all solutions except tap water and distilled water have the concentration of M.

The space environment is pretty much the opposite of the conditions that humans evolved for, to the point where an unprotected human exposed to space will die horribly in .

Investigating Electrolysis Essay - Investigating Electrolysis INTRODUCTION: In this experiment I will be investigating how the amount of copper affects the mass of the cathode.

I will do this experiment twice so that I have an average of my results so that they are accurate.
