You have 53 g of aluminum at25 degrees C.
How much heat must be added to raise its
temperature to 139 degrees C? Assume the specific
heat of aluminum is 903 J/kg · degrees C.
Answer in units of J

  • chemistry -

    q=m*c*change of t
    m=mass
    c= specific heat
    change of t= final temp- initial temp

    fill in these with your numbers and you should get the answer

  • chemistry -

    is it supposed to be a really high number?

  • chemistry -

    sorry convert your 53 grams to kg. because your specific heat capacity is in J per kg

    this should change your answer

  • chemistry -

    right. or change specific heat to 0.903 J/g.
