Question

1 Which of the following temperature can never exist A. -1°C B. -1°F C.-1K D. All of these​

Answer 1

Answer:

Explanation:-1 k is a right answer because 273 kevin is absolutely zero

Answer 2

Answer:

The temperature -1K can never exist.

Explanation:

At the temperature of zero kelvin or 0 K (minus 273 degrees Celsius) the particles stop moving and all disorder disappears. So, it is concluded that nothing can be colder than absolute zero on the Kelvin scale.

As the temperature is less than absolute zero does not exist.

Checking the options:

(a) -1°C

-1°C  can be written as 272 K.

(b)  -1°F

-1°F  can be written as 254.817 K.

(c) -1K

(d) All of these​

So, -1°C and -1°F is greater than 0 K, these temperatures exist.

Hence, the temperature -1K can never exist. Hence, the correct option is (c) -1 K.
