a platinum resistance thermometer reads 0degrees and 100 degrees at ice point and boiling point of water respectively .the resistance of platinum wire varies with celcius temperature (theeta) as Rt=Ro(1+A(theeta)+B(theeta)square)

where A=3.8 into (10raised to the power-3)

B=5.6 into (10 raised to power-7)

what would be the reading of this thermometer if placed in a liquid bath at 50 degree celcius.?

please tell me the priciples to help me do this sum and if possible even the solution

thank you
