    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!

    Question about determing specific heat capacity using 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

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

    Question about determing specific heat capacity using waterfall.

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

    Question about determing specific heat capacity using waterfall.

    It turns into heat and some sound energy! :P

    Question about determing specific heat capacity using 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 :)

    Question about determing specific heat capacity using waterfall.

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