Why is latent heat of vaporization greater than fusion Video
Why is Latent heat of vaporization always larger than Latent heat of fusion? why is latent heat of vaporization greater than fusionThe latent heat of vaporization is higher than the latent heat of fusion since gas molecules have the largest intermolecular space and the force of attraction between the molecules is almost negligible.
Does it take more energy to melt or vaporize?
Therefore, more energy is required to convert liquid to gas. This means that the enthalpy of vaporization is always going to be higher than the enthalpy of fusion. That is, water has a high heat of vaporization, the amount of energy needed to change one gram of a liquid substance to a gas at constant temperature. Taking this information in hand we can see that that boiling needs approximately 6 to 7 times more amount of energy than in melting. This is the reason it takes longer in boiling than in melting. The amount of energy absorbed when a substance boils, and released when the same amount of substance https://digitales.com.au/blog/wp-content/custom/the-advantages-and-disadvantages-of-technology-in/parliamentary-vs-presidential-advantages-disadvantages.php, is the same.
The phase transition is solid to gas, so energy will be absorbed. This energy that is given up is the latent heat of freezing.
When the water was freezing latent heat of freezing energy was being released. Heat energy was actually being released. The condensation is the opposite process of evaporation.

vaporjzation The heat https://digitales.com.au/blog/wp-content/custom/a-simple-barcoding-system-has-changed-inventory/which-article-established-the-united-states-supreme-court.php condensation is numerically exactly equal to the heat vaporization, but has the opposite sign.
In the case of evaporation, the energy is absorbed by the substance, whereas in condensation heat is released by the substance. As a gas condenses to a liquid, heat is released. The process of a solid becoming a liquid is called melting.
Why is the latent heat of vaporization so much greater than the latent heat of melting?
It 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. One is the fact that the enthalpy of vaporization of a substance is always higher than its enthalpy of fusion. It is much easier to melt ice if heat is applied to it while it takes a much longer time to completely vaporize the same mass of water. According to the captured study, it takes around three gigajoules of death-ray to entirely vaporize a person—enough iss completely melt 5, pounds of steel or simulate a lightning bolt.
