The susceptibility of magnesium at 300 K...

The susceptibility of magnesium at `300 K` is `1.2 xx 10^(-5)`. At what temperature will the susceptibility increase to `1.8 xx 10^(-5)`?

Text Solution

Verified by Experts

Since x=(C/T)`
` implies (x_1)/(x_2)=(T_1)/(T_2)`
` implies (1.2xx10^(-5))/(1.8xx10^(-5))=(T_2)/(300)`
` implies T_2= (12/18)xx300`
`=(2/3)xx300=200 K`.
