Best ResponseYou've already chosen the best response.0\[\Delta Q = m*c*\Delta T\]

Best ResponseYou've already chosen the best response.0locate c, the specific heat of aluminum, on a table... use units for mass that agree with the units of the value you have for specific heat...

Best ResponseYou've already chosen the best response.0is the specific heat for aluminum 0.920 J/(g c)? is that what ur asking for?

Best ResponseYou've already chosen the best response.0do you want me to google that in order to verify that it's the correct value or something?

Best ResponseYou've already chosen the best response.0ok so i take that and i multiply it by the mass which is 10g but how do i find the delta t?

Best ResponseYou've already chosen the best response.0so it would be negative 40?

Best ResponseYou've already chosen the best response.0ok so the formula would be 5*0.920J*40 then i would get my answer?

Best ResponseYou've already chosen the best response.0sure but the question asks how much heat is lost... so if I asked you how much money you lost in the earlier example... what would you say?

Best ResponseYou've already chosen the best response.0"lost" means "negative".

Best ResponseYou've already chosen the best response.0no lol so we would say we lost 40 thermal energy?

Best ResponseYou've already chosen the best response.0temperature decreased > heat was lost.... delta T is negative delta Q is negative delta Q = 386 J means 386 J was lost
