Question

On converting ${25}^{\circ }C,{38}^{\circ }Cand{66}^{\circ }C$
to Kelvin scale, the correct sequence of temperature will be

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

Answer 1

The correct option is A

298 K, 311 K and 339 K
The rule for the conversion of temperature from degree Celsius to Kelvin is
Temperature in Kelvin = (Temperature in ${}^{\circ }C)+273$

${25}^{\circ }C=(25+273)K=298K{38}^{\circ }C=(38+273)K=311K{66}^{\circ }C=(66+273)K=339K$
