Question

What is the kelvin temperature for 30°c?

a. 273 k
b. 293 k
c. 30 k
d. 303 k
e. 130 k

Answer 1

The Kelvin temperature for 30°C is 303 K, which is obtained by adding 273 to the Celsius temperature.

Step-by-step explanation:

The temperature of 30°C converted to the Kelvin scale is done using the formula where Kelvin (K) is equal to the temperature in Celsius (°C) plus 273.15. However, for most purposes, it is acceptable to round and use 273 instead of 273.15. Therefore, the Kelvin temperature for 30°C would be calculated as follows:

K = 30°C + 273
= 303 K

Thus, the correct answer is d. 303 K. Note that the Kelvin scale does not include the word 'degrees' - it is simply 'kelvins'. When speaking of temperature in the Kelvin scale, you would say 'three hundred three kelvins' instead of 'three hundred three degrees Kelvin'.
