Problem 82 - Chemistry: An Atoms-Focused Approach

Question

Liquid hydrogen boils at \(-253^{\circ} \mathrm{C} .\) What is the boiling point of \(\mathrm{H}_{2}\) on the Kelvin scale?

Step-by-Step Solution

Answer

Answer: The boiling point of liquid hydrogen in Kelvin is approximately 20.15 K.

Step 1: Write down the boiling point in Celsius

The boiling point of liquid hydrogen is given as \(-253^{\circ} \mathrm{C}\).

Step 2: Convert from Celsius to Kelvin

To convert from Celsius to Kelvin, add 273.15 to the given Celsius value: \(-253^{\circ} \mathrm{C} + 273.15 \approx 20.15 K\).

Step 3: Write down the boiling point in Kelvin

The boiling point of liquid hydrogen on the Kelvin scale is approximately \(20.15 K\).
