Question

The boiling point of ethane is â 88°C. This temperature will be equivalent to (a) 285 K
(b) 288 K
(c) 185 K
(d) 361 K

Answer 1

To convert temperature from °C to K, we add 273.15 in the given value.

Thus 88 + 273.15 = 361.15 K

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 $^{\circ} \mathrm{C}$ to K, we add 273 to the temperature, hence $88^{\circ} \mathrm{C}$ is equivalent to  88+273 = 361 K .
