What is the heat of vaporization of radon?
Correct answer: C. 18.0 kJ/mol
- A. 1.77 kJ/mol
- B. 9.7 kJ/mol
- C. 18.0 kJ/mol
- D. 6.5 kJ/mol
Explanation
This means that to vaporize one mole of liquid radon, 18.0 kilo joules of energy are required. This value is specitic to radon due to its unique atomic and molecular properties, which determine the energy needed for the phase change.
