Substance H 2O Spec. If 25.0 g of Al cool from 310 oC to 37 oC, what amount of energy (J) is lost by the Al?
Substance H 2O Spec. If 25.0 g of Al cool from 310 oC to 37 oC, what amount of energy (J) is lost by the Al? If 25.0 g of Al cool from 310 oC to 37 oC, what amount of energy (J) has been transferred by the Al? Heat gain/lose = q = (sp. Where T = T - T q = (0.897 J/gK)(25.0 g)(37 - 310)K Notice that the negative sign on q signals q = - 6120 J heat "lost by" or transferred OUT of Al. What does this really mean?
