I missed the test question can anyone explain what they did to solve for this.
In grinding a steel knife blade(SH=.11 cal/g*C) the metal can get as hot as 400C. If the blade has a mass of 80g, what is the minimum amount of water needed at 20C if the water is not to rise above the boiling point when the hot blade is quenched in it?
answers were: 22, 33, 44 or 55g
I tried using Q=mc[del]T then the difference of the two but didnt work that way, can anyone please help me?
TY
