Why doesn't boiling occur when a liquid is heated in a closed vessel?
Options
- ABecause the vapor pressure decreases
- BBecause the liquid becomes more dense
- CBecause the temperature does not increase
- DBecause the liquid and vapor densities become the same
Correct answer
A. Because the vapor pressure decreases
Step-by-step solution
Boiling does not occur when a liquid is heated in a closed vessel because the vapor pressure increases, indicating that the vapor pressure must increase for boiling to take place.
