Thank you for the start. One last question....what is a philosophical ideal??

what is symmetry

This is how far i got 2330g *4.184J/g degree C *(100 degree C-unk) =537,000J so 9748.72J * unk =537,000J so 537000/9748.72=55.08 so 100-55.08= Initial temp of 44.92 degrees celsius :)

The nearest would be 18. Right?

I don`t know exsactlly the anser but i do think that like you said each letter represents a number i was thinking A=1 B=2 And so on so it would be some thing like that don`t blame me though if you get it wrong i am not sure.

Thank you Ms. Sue
