Question

The steam point and ice point of a mercury thermometer are marked as 80o and 10o . At what temperature on centigrade scale the reading of this thermometer will be 59o ? (A) 70oC (B) 60oC (C) 80oC (D) none of these

(T â² - 10/80 - 10)=(TC/100) (59 - 10/80 - 10)=(TC/100) TC=70oC

Q. The steam point and ice point of a mercury thermometer are marked as $8 0^{o}$ and $1 0^{o}$ . At what temperature on centigrade scale the reading of this thermometer will be $5 9^{o}$ ?

$7 0^{o} C$

$6 0^{o} C$

$8 0^{o} C$

none of these

$\frac{T ' - 10}{80 - 10} = \frac{T _{C}}{100}$
$\frac{59 - 10}{80 - 10} = \frac{T _{C}}{100}$
$T_{C} = 7 0^{o} C$
