The freezing point on a thermometer is marked as $20^{\circ}$ and the boiling point as $150^{\circ}$ . A temperature of $60^{\circ} C$ on this thermometer will be read as.

Question

The freezing point on a thermometer is marked as 20-circ- and the boiling point as 150-circ- - A temperature of 60-circ- C on this thermometer will be read as-40-circ-65-circ-110-circ-98-circ-

For any two thermometric scales-T1-x2212-LFP1UFP1-x2212-LFP1-T2-x2212-LFP2UFP2-x2212-LFP2where LFP-xA0-and-xA0-UFP are Lower Fixed Point and Upper Fixed Point respectively-x2234-Tcelsius-x2212-0100o-T-x2212-20o130o-x21D2-T-78o-20o-98o

The freezing point on a thermometer is marked as 20∘ and the boiling point as 150∘ . A temperature of 60∘C on this thermometer will be read as.40∘65∘110∘98∘

For any two thermometric scales,T1−LFP1UFP1−LFP1=T2−LFP2UFP2−LFP2where LFP and UFP are Lower Fixed Point and Upper Fixed Point respectively.∴Tcelsius−0100o=T−20o130o⇒T=78o+20o=98o

The freezing point on a thermometer is marked as $20^{\circ}$ and the boiling point as $150^{\circ}$ . A temperature of $60^{\circ} C$ on this thermometer will be read as.
