a$.$ Graph # $1$ : Draw $4$ curves $($PRT$100,$ Thermistor, Thermocouple and Liquid in Glass thermometer temperatures on y$-$Axis$)$ on one paper versus PRT$100$ temperature on x$-$Axis. Find $\%$ Error of Thermistor, Thermocouple and Liquid in Glass thermometer compared to PT$100$ reading of $70$C$.$

b$.$ Graph # $2$ : Draw PRT$100$ temperature on y$-$axis versusThermistor resistance on x$-$axix $.$ also draw best fit curve and find its equation from EXEL. Using this equation find temperatures corresponding to resistances of $1384$ohms, $,961$ohms and $87$ ohms. Find $\%$ Error in comparison to $35$C$,45$C and $55$C of PRT$100$ readings.
