Heating water

  1. Aug 24, 2008 #1
    how much water would 1000 MW/J heat from 18 degrees to 30 degrees?

    i am unsure of what formula [is there is one] to use...

    so any help would be GREAT!

    TIA:smile:

    Hint: What's the specific heat of water? (What kind of units are MW/J? Did you mean Joules?)

    i have the specfic heat of water.... and the MW/J was my way of saying mega watts or joules.

    the specific heat i have is 4.184 J g–1 K–1

    what i cant figure out is how to get the amount of water. and i am not sure of what sort of answer i am going to get, or if the answers i am getting from playing around are correct.

    i think i am confusing myself....:uhh:

    What's the definition of specific heat? Look it up!
    Those aren't the same thing, you know. :uhh: (Watts = power; Joules = energy.)
