Question

Figure shows three temperature scales with the freezing and boiling point of water indicated. A change of `25^(@) R, 25^(@) S and 25^(@) U` is denoted by `x_(1), x_(2), x_(3)` respectively. Which of the following is correct?

A. `x_(1) gt x_(2) gt x_(3)`
B. `x_(2) lt x_(1) lt x_(3)`
C. `x_(3) lt x_(2) lt x_(1)`
D. `x_(2) gt x_(3) gt x_(1)`

Answer 1

Correct Answer - D
`Delta 1^(@)R = Delta 1^(@)K`
`Delta 1^(@)S = Delta (100^(@))/(70)k`
`Delta 1^(@)U = Delta (100^@)/(75) k`
`rArr 25^(@)S gt 25^(@)U gt 25^(@)R`.
