On converting 25°C, 38°C and 66°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

Ans. A

Sol.

Celsius scale of temperature is based on water and its state. The melting point is taken as zero reference and boiling point of water is taken as 100.

Kelvin scale of temperature is known as absolute temperature scale.

These two scales can be easily related by a linear relation.

If temperature in Celsius scale is X then the same temperature in Kelvin scale will be X +273.

We have 25°C, 38°C and 66°C.

On conversion, these temperatures will be 298K, 311K and 339K respectively.

Hence the correct answer will be option A
