The increasing vapor pressure caused by heating a liquid is due to___________?
Correct answer: D. increasing kinetic energy of molecules
- A. increase inter-molecular interactions
- B. increasing potential energy of molecules
- C. decreasing surface tension
- D. increasing kinetic energy of molecules
Explanation
Heating gives liquid molecules greater kinetic energy, allowing more of them to escape from the surface into the vapour phase. This increases the equilibrium vapour pressure.
