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

150 K

B

200 K

C

250 K

D

20 K

Text Solution

Verified by Experts

The correct Answer is:
B
`chi=(C )/(T)`
`implies " "(chi_(1))/(chi_(2))=(T_(2))/(T_(1))implies(1.2xx10^(-5))/(1.8xx10^(-5))=(T_(2))/(300)`
`implies" "T_(2)=(12)/(18)xx300=200K`
