A sudden change in slope or discontinuity in the graph would indicate a phase change taking place. This can be seen as a sharp point or step-like feature in the graph.
The plateau on the graph indicates that the water has reached its boiling point and is transitioning from liquid to gas phase. During this phase change, the temperature remains constant while the water absorbs heat to break intermolecular bonds and change its state.
chemical reaction taking place, a change in temperature or pressure, or the formation of a new phase in a solution. It can also be used as a method for separating components in a mixture or as a way to purify a solution.

A horizontal line on a phase change graph means there has been no change. Often longer periods of research are needed to see significant change.

It is because that is when the change is occurring, and the diagonal part is when the process has already happened
A graph with two flat sections joined by a slope represents a phase change. The flat sections indicate a constant temperature during a phase change, such as when ice is melting or water is boiling. The slope represents a temperature increase or decrease during the transition between phases. In a graph, you would mark the flat section for ice melting and boiling water where the temperature remains constant.
The graph that best represents a change of phase from a gas to a solid would show a decrease in temperature over time as the gas loses energy and transitions into a solid state. The temperature remains constant during the phase change itself due to the energy being used to break intermolecular bonds rather than increase temperature.

Thermal energy (heat)
A shallow slope on a phase change graph indicates that a relatively small amount of heat is required to change the temperature of the substance during a phase change, such as melting or boiling. This typically occurs when the substance is undergoing a phase transition, where energy is being used to overcome intermolecular forces rather than increasing temperature. Consequently, the shallow slope reflects a higher specific heat capacity during the phase change.
This a phase change, from liquid to gas.
To determine the phase constant from a graph, identify the horizontal shift of the graph compared to the original function. The phase constant is the amount the graph is shifted horizontally.
