lol i can't help u with it all.. but some guidelines
Weight candle before/ after (to find out how many moles used)
record temp before/ after
that's about all...
then u needa do calculation. u know specific heat capacity is 4.18? bleh forgot.. somethine around that.. then u know the mass of water and temp change
u can then come up with the energy change
then u jus divide that by the no. of moles used of the candle
