Which of the following is described by the equation h2o(s)+ heat=h2o(i) a freezing melting condensing evaporating

Consider the heating curve of h2o and line segments a, b, and c. several changes are taking place at a, b, and c. all but one would be an appropriate description as e move through segments a, b and then c.
