A platinum resistance thermometer records 3.0$\Omega$ at 0oC and 8.0$\Omega$ at 100oC. If it records 6.0$\Omega$ in a certain environment, The temperature of the medium is

Answer Details

8$\Omega$.....100oC

6$\Omega$.....$\theta$oC

3$\Omega$.....0oC

$\frac{6-3}{8-3}$ = $\frac{\theta -0}{100-0}$

therefore, $\theta$ = 60oC
