a) Draw a heating curve (qualitative) starting with ice at -20 degrees C going to steam at 200 degrees C. Indicate the solid, liquid, and gas states, and the melting and boiling points.
b) Given 1000.0 g of ice, calculate the energy required for each step in 2a.
c) From the information in 2b, draw the heating curve to scale.
d) Which step takes the most energy?
