You want to know the temperature of a liquid, so you use a resistor as a
thermometer. You place the resistor in ice water (0 Deg C) and measure
its resistance to be 120 Ohms. You then place the resistor in boiling
water (100 Deg C) and measure its resistance to be N1 Ohms.
Finally you place the resistor in the liquid and measure its resistance
to be n2 Ohms. If the temperature of the liquid is
n3 Deg C,
what is n3? Note that n1 and n2 have
units of Ohms, and n3 is in Deg C.
