- Graph 1.0 shows a gradual increase in skin temperature of the hot test subject (Sara Withers) throughout the duration of the 20 minutes with a peak of 33.6 °C at 18 minutes, a 3.7 °C increase from the skin temperature reading at the commencement of the experiment, 29.9 °C. The graph also shows a substantial gradual decrease in skin temperature of the cold test subject (Kirsty Hatton) throughout the duration of the 20 minutes with an all-time low of 20.8 at 6 minutes, a decrease of 9.7 °C from the skin temperature reading at the commencement of the experiment, 30.5 °C, and a low of 22.9 at 20 minutes, a …show more content…
This trend shown contrasts with the trend of that of the skin temperature of the hot subject (Sara Withers) also shown on the graph. The trend shown by the graph for the skin temperature of the hot subject (Sara Withers) is an increasing trend – the skin temperature increases with the passing of time. Graph 1.2 shows a gradual increase in skin temperature of the hot test subject (Sara Withers) throughout the duration of the 20 minutes with a peak of 33.6 °C at 18 minutes, a 3.7 °C increase from the skin temperature reading at the commencement of the experiment, 29.9
