For the equation q=cΔt, q=100KJ, initial temp=20 degrees celsius, final temp=31.4 degrees celsius and I need to find c. Do I need to convert the q value from KJ to J?

  • Chemistry -

    convering, depends on the units you want.

    c=q/deltaT=100kj/11.3 C= 8.85kJ/C

    and

    c= 8850J/C

    you have to specify units, and both answers are correct.
