Question 1

A piece of iron (mass = 25.0 g) at 398 K is placed in a styrofoam coffee cup containing 25.0 mL of water at 298 K. Assuming that no heat is lost to the cup or the surroundings, what will the final temperature of the water be? The specific heat capacity of iron = 0.449 J g-1 °C-1 and water = 4.184 J g-1 °C-1.
◦ 308 K
◦ 348 K
◦ 325 K
◦ 287 K
◦ 388 K

Question 2

A student is preparing to perform a series of calorimetry experiments. She first wishes to determine the calorimeter constant (Ccal) for her coffee cup calorimeter. She pours a 50.0 mL sample of water at 345 K into the calorimeter containing a 50.0 mL sample of water at 298 K. She carefully records the final temperature of the water as 317 K. What is the value of Ccal for the calorimeter?
◦ 99 J K-1
◦ 28 J K-1
◦ 21 J K-1
◦ 76 J K-1
◦ 19 J K-1
