What happens to the energy added during a phase change?
Ivanshal [37]

Answer:You're answer is D: it is converted to kinetic energy

Explanation:

During a change of phase, the average kinetic energy of the molecules stays the same, but the average potential energy changes. ... My interpretation is that during a phase change, the temperature remains equal, but the kinetic energy of its particles increase/decrease.

Compared to the normal freezing point and boiling point of water, a 1-molar solution of sugar in water will have a
marysya [2.9K]

Answer :

  • Boiling point of the sugar solution will be higher than that of water's boling point.
  • Freezing point of the sugar solution will be lower than that of water's freezing point.

Explanation:

  • Boiling point of a liquid is defined as temperature at which vapor pressure of liquid becomes equal to the atmospheric pressure.

Boiling point of solution is always higher than that of the pure solvent

Vapor pressure increases with increase in temperature which means sugar solution will be heated more to make vapor pressure equal to atmospheric pressure.

  • Freezing point is defined as temperature at which solid and liquid phase are at equilibrium or temperature at which vapor pressure of liquid becomes equal to the vapor pressure in its solid phase.

Freezing point of solution is always lower than that of the pure solvent.

Lower the temperature, lower will be the vapor pressure which sugar solution solution will get freeze at lower temperature than that of the water.
