Question

On converting 308 K, 329 K and 391 K to Celsius scale, the correct sequence of temperatures will be (a) 33°C, 56°C and 118°C
(b) 35°C, 56°C and 119°C
(c) 35°C, 56°C and 118°C
(d) 56°, 119°C and 35°C

Answer 1

Answer:

(c) Is the correct answer..

Explanation:

Subtract 273 K from others..

Because 273 K= 0°C

Answer 2

Explanation:

• When measuring temperature using the temperature scale of Celsius (C), $0^{\circ} \mathrm{C}$ is the freezing point of water and $100^{\circ} \mathrm{C}$ is the boiling point of water.
• In the Kelvin (K) temperature scale, 0 K is considered absolute zero where water molecules are completely frozen which corresponds to $-273^{\circ} \mathrm{C}$.
• Therefore to convert temperature from Kelvin to $^{\circ} \mathrm{C}$, we subtract 273 from the temperature, hence

        $308-273=35^{\circ} \mathrm{C}$

        $329-273=56^{\circ} \mathrm{C}$

        $391-273=118^{\circ} \mathrm{C}$
