Heres the problem. Im having trouble figuring it out.

If 100 grams of boiling water at 100 *C is poured into a 100 gram platinum beaker at 0*C an intermediate temperature will result. Knowing the specific heat of water is approximately 32 times greater than that of platinum, approximate the resulting temp.

Specific Heat of water is 4.18 J/g *C
Platinum is 0.131 J/g *C

Thanks in advance

Try this formula.. Not sure if its what you exactly need.. And I honestly dont because I think you want he temperature of the equilibrium.. does is give any hints as to what the


Eq.

(Specific heat of water)x(Mass of water)x(T(final) - T(initial) of water) =
-(SH of Platinum) x Mass of Platinumx (Delta Temp)


^^ yeah that should work actually.. You need the final heat of substance and you have the Initial temp, mass, and SH

2nd edit: Wait You have to missing variables.. you dont know either final temps.. wtf! Check your problem or previous problems for water's final heat!

A day late dude haha thanks though. I figured it out and ya i forgot the final temps..
