2 kg of iron at an initial temperature of 1200C is placed into 4 kg of water at an initial temperature of 300C.
What is the final temperature of the mixture when
thermal equilibrium is reached?
[Specific heat capacity of water = 4 200 J kg 1 oc 1
and specific heat capacity of iron = 450 J kg I OC-II​

4. now look at the green lines you created by connecting the three boiling point data points and the three melting point data points. for each of these lines, describe any trends you see. 5. locate the elements on your periodic table that you circled in green on your graph. what term or description would you use to identify these elements with respect to the periodic table? 7. using the room temperature line (orange line) and your periodic table, make lists that identify the state of matter (gas, liquid, or solid) in which each element you plotted exists at room temperature. explain your answers.
