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:

For plotting temperature time graph for a hot body as it cools to room temperature, a student is to choose one each from each of the following pairs. A: Calorimeter (i) blackened from outside (ii) polished from outside B: Base for keeping the calorimeter (i) insulated (ii) metallic In order to get the correct graph he should prefer to choose:
