The platinum wire has resistance of 2 ohms at the temperature of melting ice, 2.778 ohms at temperature of boiling water under standard pressure and 2.54 ohms at the boiling point of a liquid. Find the platinum scale temperature (t_(p)) and the corresponding correct temperature (t). Assume delta=1.5 for pure platinum.

1.	The platinum wire has resistance of 2 ohms at the temperature of melting ice, 2.778 ohms at temperature of boiling water under standard pressure and 2.54 ohms at the boiling point of a liquid. Find the platinum scale temperature (t_(p)) and the corresponding correct temperature (t). Assume delta=1.5 for pure platinum.
Answer» <P> ANSWER :`t_(p)=69.41`and `t=69.09^(@)C`
