When temperature is changing with respect to the time in the given graph, then substance B was undergoing a change of state.

What is change of state?

When any substance converts from one form of matter to the other form, then this phenomenon is known as change of state.

In the given figure a graph represents the change in temperature of substances A, B, C and D with respect to the time. Temperature of the substances A, C & D keep continuous changing with respect to the time. But substance B shows change in state because it absorbs the heat to convert in another state by breaking old bonds and making new bonds and showing showing no change in temperature.

Hence, substance B was undergoing a change of state.
