    Are you sure? Did you convert the temp into kelvin?

    794-373/794 = 0.53

    that specific heat was easy man, just had to realise the gradient times the mass time C gave 29.9 Joules per second oh and remeber to convert the mass from grams!

    well the kelvin scale is the same as celcius isnt it just shifted 273, so i am assuming either answer will be acceptable, the equation works for both scaled, just your final answer will differ by 273

    there you go, another mistake by me, i din convert it thinking tht as the joules r not kiljoules i dn need to convert tht damn thing..
