Which of the following statements about the process of melting of a solid are true? The temperature of the solid will
I. remain steady until melting starts.
ll. keep rising until melting starts,
Ill remain steady as melting proceeds.
V, keep rising as melting proceeds.
During change of state, there is no change in temperature, for a solid to change to liquid, heat must be supplied and it starts rising again after melting has taken place. therefore, the temperature rises before melting takes place remains steady during melting, and keeps rising after melting.
