How much heat is needed to raise the temperature of 50g of a substance by 15c when the specific heat is 0.92?
kirill [66]
The  heat  needed  to  raise  the  temperature   of  50g  of  substance  by    15 c   is  calculated as   follows

Heat  =   mc delta  T

m= mass   (50g)
c=  specific  heat  capacity  (0.92)
delta T=  change  in  temperature(  15 c)

heat  is  therefore=   50   x  0.92  x  15  =  690   

Nb:
  my   answer  has  no  units  since   the   given   specific  heat  capacity  has   no  units
