What is the final temperature of a system of iron and water if a piece of iron with a mass of 25g at a temperature of 75C is dropped into an ainsulated sontainer of water at 35.6C? The mass of the water is 150g. The specific heat of iron is 0.449J/g.C, and the specific heat of water is 4.184 J/g.C.

Let the final temperature be T
Heat lost or absorbed = mass(g) x specific heat (J per gram per degree) x change in temperature (degrees)
Heat lost by iron equals heat gain by water
25g x 0.449 J g-1 degree-1 x (75 - T) degrees = 150g x 4.184 J g-1 degree-1 x (T - 35.6) degrees
Work out the numbers and do the arithmetic. That's all. Good luck.
