A platinum resistance thermometer reads `0^@ C` when its resistance is `80 Omega and 100^@ C` when its resistance is `90 Omega`. Find the temperature at which the resistance is `86 Omega`.

The electrical resistance of pure platinum increases linearly with increasing temperature over a small range of temperature . This property is used in a Platinum resistance thermometer. The relation between R_(theta) (Resistance at theta K) and R_(0) (Resistance at theta_(0)K ) is given by R_(theta)=R_(0)[1+a(theta-theta_(0))] , where alpha= temperature coefficient of resistance. Now, if a Platinum resistance thermometer reads 0^(@)C when its resistance is 80Omega and 100^(@)C when its resistance is 90 Omega find the temperature at which its resistance is 86Omega .
