Question

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

​

Answer 1

Heyaa dear here is your answer:

The correct sequence of temperature will be 298 K, 311 K and 339 K .On converting 25°C, 38°C and 66°C, to kelvin scale, we get the following temperatures 25°C + 273 = 298 K ⇒ 38°C + 273 = 311 K ⇒ 66°C + 273 = 339 K. The correct sequence of temperature will be 298 K, 311 K and 339 K.

Answer 2

Kelvin is the SI Unit of measurement of temperatures. It is represented with the Unit Kelvin 'K'.

Temperatures can be converted from Celsius to Kelvin by adding 273 to the the Celsius Scale.

We have been given 3 temperatures here which are in the Celsius Scale.

25°C, 38°C and 66°C

To convert all of them to the Kelvin Scale, add 273 to all of them.

25 + 273 = 298 K

38 + 273 = 311 K

66 + 273 = 339 K

So, the correct answer is Option (A) 298 K, 311 K and 339 K !
