Please answer parts (a) and (b) by referring to the graph plotted as shown below thanks.

i) Principle of Saturation Pressure Measurement i) Principle of Saturation Pressure Measurement (a) Comment on the shape of the graphs obtained. Discuss any differences between the actual temperature and the experimental temperature indicated by the T1. (b) What you read from the temperature display could have some delay as compared with the actual current temperature, due to the design of the temperature sensor. Thermal lag is the time required for the reading of the temperature be captured by the sensor from the point where the actual temperature occurs. Estimate the thermal lag of the thermometer from the graph plotted. Discuss how the effect of thermal lag could be reduced
