MCQ
On converting $25^\circ C, 38^\circ C$ and $66^\circ C$ to Kelvin scale, the correct sequence of temperatures will be:
  • ✓
    $298K, 311K$ and $339K$
  • B
    $298K, 300K$ and $338K$
  • C
    $273K, 278K$ and $543K$
  • D
    $298K, 310K$ and $338K$
✓

Answer

Correct option: A.
$298K, 311K$ and $339K$
To convert the temperature scale from Celsius scale to Kelvin scale, just add $273K$ to the given values. Therefore, the temperature in Kelvin scale of $25^\circ C, 38^\circ C$ and $66^\circ C$ will be $298K, 311K$ and $339K,$ respectively.
