Solution

Given,

T = 200K,

χ1 = 1.8 × 10−5

χ1 - χ2 = 6 × 10-6

To Find: Required temperature (T2)

Formula: χT=constatnt

Calculation :

χ1 - χ2 = 6 × 10-6

χ2 = 1.8×10-5 - 0.6×10-5

χ= 1.2 ×10-5

From formula,

 ∴χT = constant

χ1T1 = χ2T2

`T_2 =(chi_1T_1)/chi_2`

`T_2=(1.8xx10^-5xx200)/(1.2xx10^-5)`

`T_2 = 300K `

The required temperature is 300 K.

  Is there an error in this question or solution?
