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

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

is it supposed to be a really high number?

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

this should change your answer
