Explanation / Answer

1) The purpose of this lab is to elicit the sense of touch, smell and taste. For example in the experiment for touch, when the hand placed in hot water for one minute and placed in normal water, it feels cold. Similarly, the hand which was placed in cold water for one minute when placed in lukewarm water, the hand feels hotter.
