S=substance i=iron a=aluminum g=gold c=copper

and in case numbers are too messy :P 0.46 0.90 0.13 0.39

we have the subsequent relationship: $c = \frac{1}{m}\frac{{\Delta Q}}{{\Delta t}}$

6. Michele_Laino

c is the specific heat

ohh okay! what do we plug in? :/

8. Michele_Laino

now we can see the ratio: $\frac{{\Delta Q}}{{\Delta t}}$ as a heating speed so the subsatnce with lwer specific heat, will heat up as the slowest

lower*

ohh so our solution will be gold?

11. Michele_Laino

yes!
