Temperature-time graphs

Equal masses of two liquids A and B contained in vessels of negligible heat capacity are supplied heat at the same rate. The temperature-time graphs for the liquids are shown in the figure. If S represents specific heat and L represents latent heat of liquid, then

Can there be a temperature- time graph as follows ? Justify your answer.

For the following temperature-time graph, in which region the state of material changes

The temperature-time graph obtained when hot water is allowed to cool resembles the graph given in one of the following figures. The correct figure is:

A well insulated substance in solid state is heated at a constant rate until it vaporizes completely. The temperature-time graph of the substance is shown below . Which of the following statements is//are true?

Two students X and Y have to do their experiment on plotting the temperature-time graph for a hot body as it cools to room temperature. They do their experiments in the same lab, using completely identical apparatus, take equal amounts of tap water heated up to the same temperature, start their observations simultaneously and note the temperature values at identically spaced intervals of time. Their temperature-time graphs, plotted on a given graph paper, with the same given choices of scales along the axis, are however, as shown: The following could be the reason for this difference: (A) Use of an overhead fan by student X. (B) Use of an overhead fan by student Y. (C) Less frequent stirring of water by student X. (D) Less frequent stirring of water by student Y. The most likely reason is:
