Question

The absolute scale of temperature is Kelvin. water freezes at 273 k. and boils in 373 k. Hence find out the value of 40 degrees C temperature in the kelvin scale. a)233 k b)323 k c)300 k d)313 k

Answer 1

Answer:

313.15 kelvin

Explanation:

HEY there, it is very easy

Water freezes at 0 degree C and boils at 100 degree C,

that means 273.15 K= 0 degree C and 373.15 K= 100 degree C

So 40  degree C = (40 + 273.15 ) K = 313.15 K.

Hope it helps.

Answer 2

Answer:

The value of 40°C in kelvin scale is equal to 313.15 kelvin.

Explanation:

Relationship between temperature in degree and in kelvin:

              $T(Kelvin) = 273.15 + T(^{o}C)$

Temperature 40°C in kelvin scale $= 273.15+40 = 313.15 Kelvin$

Therefore, 40°C will be 313.15 kelvin in kelvin scale. So the option d is correct.
