    Wow, that comment confused me more :D

    What Forms at the Anode During Electrolysis of Molten Chromium Sulphate?

    During the electrolysis of a molten sulphate, for example Chromium sulphate. At the cathode, chromium forms but what forms at the anode? Is it sulphur dioxide and oxygen?

    Thanks man!

    Specific heat capacity of water in a 210 m waterfall

    Ok so since p.e. mgh Then p.e. is 1kg * 10m/s * 210 2100 J And this is converted to 2100 J of kinetic energy Since Eh = mc *temperature change 2100 = 1 * c *.5 which is 4200 :D

    Specific heat capacity of water in a 210 m waterfall

    When calculating, you are able to use any value for mass?

    Specific heat capacity of water in a 210 m waterfall

    I think heat is 1/2 mv(squared), but don't know the one for potential energy.

    Specific heat capacity of water in a 210 m waterfall

    It turns into heat and some sound energy! :P

    Specific heat capacity of water in a 210 m waterfall

    Well, at the top, there would be potential energy and as it falls to the bottom, it would gain kinetic energy. Since kinetic energy is linked to temperature, that explains the temperature rise. But still the problem is linking everything together to give the answer. LOl :)

    Specific heat capacity of water in a 210 m waterfall

    Homework Statement The temperature at the top of a popular waterfall is 22.0 degrees celsius. The temperature at its base, 210 m lower, is 22.5 degrees celsius. 1)Caluclate the specific heat capacity of the water. 2) If the waterfall was twice as tall, determine by how much the water...
