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. The specific 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

Solutions

Expert Solution

heat lose of iron = Heat gain of water

mct = mct

heat lose of iron

q =

q = mct

= 1.5*0.449*(95-57.8) = 25J

Heat gain of water = 25J

b.) 25 J
