Question

Two steel balls P and Q have same readings when measured by thermometers of Celsius readings and Fahrenheit readings respectively. Then,

• A. Ball P has greater temperature than ball Q
• B. Ball P has lower temperature than ball Q
• C. Both the balls P and Q have same temperature
• D. None of these

Answer 1

Answer: (C)

Both the balls P and Q have same temperature

As both the thermometers show the same reading of temperature i.e $-{40}^o$.
Relation between ${}^{o}C$ and ${}^{o}F$ is given by
$\frac{C}{100}=\frac{F-32}{180}$
