I solved it and got 295 k for temperature which should be a right answer since water didnât lost heat, Am I right?
a A piece of iron (mFe 5.0 g) at 398 K is placed in a coffee cup containing 25.0 mL of water at 298 K. Assuming that no heat is lost to the cup or the surroundings, what is final temperature of water? The specific heat capacity of iron = 0.449 J/g·°C and water = 4.18 J/g·°C; d (H2O) = 1.00 g/mL.
