Given the EÂ° values for two half reactions, you can easily predict the potential difference of the corresponding cell: simply add the reduction potential of the reduction half-cell to the negative of the reduction potential (that is, to the oxidation potential) of the oxidation reaction.
How to Melt Glass With a Torch. Glass melting has a long history, going back to approximately 3000 BC. In these early times, glass was melted to decorate vases. Glass is made up of silica, sodium carbonate and calcium carbonate. Most glass melts at 1400 to 1600 degrees Farenheit. Nevertheless, there are specialized glasses that will melt at as low as 900 degrees.
I don't really think that it'll be possible to melt an ice cube by Kinetic Energy in the absolute absence of any kind of Friction. Although, I'm unsure about Potential Energy but I think that it is not possible to change the Ice's Temperature just by changing the Potential Energy.
