Question

A 1.5g iron nail is heated to 95.0 *C and placed into a beaker of water. Calculate the heat gained by the water if the final equilibrium temperature is 57.8 *C. Thespecific heat capacity of iron= 0.449 J/g *C; of water= 4.18 J/g *C.

Choose the answer from the following but show work.

a.) 6.0 J
b.) 25 J
c.) -25 J
d.) 39 J
e.) -39 J


would you please show how you came up with the answer, THANKS.
