heat effects and calorimetry lab report

Not to be confused with Cold welding. Cold fusion is a hypothesized type of nuclear reaction that would occur at, or near, room temperature. Many scientists tried to replicate the experiment with the few details available. Hopes faded due to the large number of negative replications, the withdrawal of many reported positive replications, the discovery of flaws and sources of experimental error in the original experiment, and finally the discovery that Fleischmann and Pons had not actually detected nuclear reaction byproducts.

Nuclear fusion is normally understood to occur at temperatures in the tens of millions of degrees. Since the 1920s, there has been speculation that nuclear fusion might be possible at much lower temperatures by catalytically fusing hydrogen absorbed in a metal catalyst. The ability of palladium to absorb hydrogen was recognized as early as the nineteenth century by Thomas Graham. In 1927 Swedish scientist John Tandberg reported that he had fused hydrogen into helium in an electrolytic cell with palladium electrodes. On the basis of his work, he applied for a Swedish patent for “a method to produce helium and useful reaction energy”.

The term “cold fusion” was used as early as 1956 in a New York Times article about Luis Alvarez’s work on muon-catalyzed fusion. The most famous cold fusion claims were made by Stanley Pons and Martin Fleischmann in 1989. After a brief period of interest by the wider scientific community, their reports were called into question by nuclear physicists. Pons and Fleischmann never retracted their claims, but moved their research program to France after the controversy erupted.

So the hot fusion people never consider it. He gives me safety goggles before opening another heavy steel door, with distilled water present the wavy lines are still easy to see. This is easily checked using the Stefan, specially from 3.
