← ScienceWhich outcome occurs when increased pressure is applied isothermally during the transition within boiling liquid?
A)Vapor collapses; liquid volume sharply decreases✓
B)Temperature increases; latent heat absorption occurs
C)Surface tension rises; bubble equilibrium shifts
D)Viscosity declines; convection heat flux stagnates
💡 Explanation
Increased pressure causes vapor to collapse as the water boils; Le Chatelier's principle favors the liquid phase. This is because increased pressure favors the denser phase; therefore vapor collapses and liquid volume decreases rather than temperature increases or phase equilibria shift.
