A brief history of what science thought about the sun can be found here . It is reasonable that once thermodynamics advanced to the point of measuring and calculating energies the discrepancy between heat output of the sun and the age of the earth had to be explained. They tried with gravitation, but until the discovery of nuclear energy and E=m*c^2 it ...
Magnesium is flammable due to the fact is has hydrogen. When the hydrogen and water combine including the magnesium that is not a good combination and the water spreads causing more issues than there already is.
The conclusion is correct: for any system containing a single reaction, there exists an equilibrium (with detailed balance) for any values of the rate constants. I'm not sure what's meant exactly by "equilibrium tools," but it's true to say that there's no real difference in the kinetics of an equilibrium or non-equilibrium system if it only contains one ...
Hmmn, an interesting question. The most logical answer is that nothing would happen, since there is nothing to react with. But in science, it all boils down to empirical evidence. Which can only be acquired with experiments.
As pointed out in detail in this article, the time variation of dimensional constants has no operational meaning.
When you heat An ice cube over a flame then heat is absorbed due to conduction and heat flows one sidedly only however in a micro wave the electromagnetic radiations have a greater penetrating power and they start moving dipoles present in ice because of which there is an increase in their vibrational energy, now because of friction between layers heat is ...
Usually, the microwaves are too weak to heat anything to a plasma state. However, if you bypass the manufacturer’s instructions and turn on the microwave with nothing in it to absorb energy, the microwave energy density will be much higher than normal. Now, the reason you cut the grape in half is: "Now it turns out that grapes are just the right size to ...
I will quickly post an answer here and will edit/expand on the answer with time. I used the model for nitrogen gas viscosity based on the PhD thesis by Kegang Ling from Texas A&M university, 2010 The model requires temperature and density. Density was calculated using the real gas law. The real gas law requires the compressibility factor of gas at ...
