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)`?

A

150K

B

200K

C

250K

D

20K

Text Solution

Verified by Experts

The correct Answer is:
B
We know that , `chi_(m)=(C)/(T)`
`implies (chi_(1))/(chi_(2))=(T_(2))/(T_(1))`
`implies (1.2 xx 10^(-5))/(1.8 xx 10^(-5))=(T_(2))/(300) `
`implies T_(2)=(12)/(18) xx 300 =200K `
