Question

Which one among the following denotes the smallest temperature?
1.1°on celsius scale
2.1°on kelvin scale
3.1°on fahrenheit scale
4.both 2 and 3

Answer 1

The smallest temperature is 1˚ on Kelvin scale.

Explanation:

To understand this, we will convert all given temperatures to Kelvin.

1˚C = 274.15 K

The temperature in K = Given temperature in ˚C + 273.15

Here, we are given temperature in ˚C as 1.

So, the temperature in K is

$\Rightarrow$ 1 + 273.15 = 274.15 K

1˚F = 256 K

This is because, temperature in K = Given temperature in ˚F + 459.67 $\times \frac{5}{9}$

Here, the given temperature in ˚F= 1

So, temperature in K= $(1+459.67)\times \frac{5}{9}$  =256K

So, 1˚C > 1˚F > 1 K

So, 1 Kelvin is the smallest temperature.
