Question

The freezing point on a thermometer is marked as 20⁰ and the boiling point as 150⁰. A temperature of 60⁰C on this thermometer will be read as –

• A. 40⁰
• B. 65⁰
• C. 98⁰
• D. 110⁰

Answer 1

Answer: (C)

98⁰

Answer 2

$\frac{\theta - 20}{150 - 20}$ = $\frac{60 - 0}{100 - 0}$

q – 20 = $\frac{13}{10}$ × 60 = 78

q = 98⁰
