Question

If the temperature of a gas in Kelvin scale is 546 K. Then the temperature of this gas at Celcius and Fahrenheit scale will be:

• A. $573F$
• B. $523F$
• C. $500F$
• D. $223F$

Answer 1

Answer: (B)

$523F$

If the temperature of a gas in Kelvin scale is 546 K. Then the temperature of this gas at Celsius and Fahrenheit scale will be ${273}^{\circ }$C and $523$ F respectively.
$T=546K=-273{}^{o}C=273{}^{o}C$
$T=273{}^{o}C=273\times \frac{9}{5}+32=491+32=523F$
