Question

What is the correct sequence of temperature in Kelvin scale which will be obtained by converting ${25}^{o}C,{38}^{o}C,{66}^{o}C$ to Kelvin scale?

• A. $298K,311K$ and $339K$
• B. $298K,300K$ and $338K$
• C. $273K,278K$ and $543K$
• D. $298K,310K$ and $338K$

Answer 1

The correct option is A $298K,311K$ and $339K$

$0^{o}C$ is equal to $273$ Kelvin.
${25}^o$C in kelvin will be $25$ + $273=298$ K.
${38}^o$ C in kelvin will be $38$ + $273$ = $311$ K.
${66}^o$ C in kelvin will be $66$ + $273$ = $339$ K.
On converting ${25}^o$C, ${38}^o$C and ${66}^o$C to Kelvin scale, the correct sequence of temperature will be $298$ K, $311$ K and $339$ K.
