You have a small container of solid ice water, H2O, currently in A on the graph. You choose to increase the amount of thermal energy in the system in two steps. In step 1, you add energy so that it goes to B. In step 2, you add energy so that it goes to C. Which choice most accurately describes what you will observe?
(A) In Step 1, you will observe the temperature of the solid water will increase until it gets to B. While in B, the temperature will continue to increase and the solid water will start melting into liquid water. In step 2, the ice water will completely melt so that in C it is all liquid water. The temperature will remain constant while it’s in C.

(B) In Step 1, you will observe the temperature of the solid water will increase until it gets to B. While in B, the temperature will continue to increase and the solid water will start melting into liquid water. In step 2, the ice water will completely melt so that in C it is all liquid water. The temperature will increase if the energy increases while it’s in C.

(C) In Step 1, you will observe the temperature of the solid water will increase until it gets to B. While in B, the temperature will remain constant but the solid water will start melting into liquid water. In step 2, the ice water will completely melt so that in C it is all liquid water. The temperature will increase if the energy increases while it’s in C.

(D) In Step 1, you will observe the temperature of the solid water will remain constant until it gets to B. While in B, the temperature will increase and the solid water will start melting into liquid water. In step 2, the ice water will completely melt so that in C it is all liquid water. The temperature will increase if the energy increases while it’s in C.
