    Why do water streams get thinner as they fall?

    Homework Statement Develop an equation that will allow you to determine the radius of the stream (r) at any distance (y) below the rim of the faucet. It would seem that the initial velocity of the water coming out of the faucet and the acceleration due to gravity have something to do with the...

    Amount of energy required to split zinc-oxide

    What temperature would it have to get to split. Also would the amount of energy to electrolyze it decrease because of the temperature?

    Amount of energy required to split zinc-oxide

    How could I split zinc-oxide into zinc and oxygen? The zinc-oxide would be at 2500 degrees Celsius. Because it is as such a high temperature, would that reduce the amount of energy that I would need to put into separate the two? Thanks!

    What Are the Key Questions About Thermite Reactions?

    I have three questions about thermite. 1. Is hydrogen released when thermite is placed in water or is it just steam? 2. How can I separate the aluminum oxide from the iron after the reaction? 3. Can the aluminum oxide be split apart into oxygen and aluminum?Any knowledge would be greatly...

    Any type of material that expands with electricity?

    I have read about the smart metals but I was looking for something that does not need to be heated. and for the quartz how much does it actually expand when the current is applied?
