How much kinetic energy does liquid have

WebWater’s heat of vaporization is around 540 cal/g at 100 °C, water's boiling point. Note that some molecules of water – ones that happen to have high kinetic energy – will escape … WebTranscribed Image Text: What happens when the kinetic energy of particles in a liquid state increases? A The particles vibrate more slowly, causing the forces of attraction holding them together to increase, resulting in a solid. C D The particles vibrate fast enough to overcome the forces of attraction holding them together and become a gas.

WebIt requires energy for a solid to melt into a liquid. Every pure substance has a certain amount of energy it needs to change from a solid to a liquid. This amount is called the enthalpy of fusion (or heat of fusion) of the substance, represented as Δ Hfus. WebLiquid particles are less ordered and more spread out than solid particles because the intermolecular forces are weaker. If the surface particles of the liquid have enough kinetic energy, they can overcome these attractive forces and escape into gas state.
