Web8 de ago. de 2024 · When 1 mol of water vapor at 100 o C condenses to liquid water at 100 o C, 40.7 kJ of heat is released into the surroundings. H 2 O ( l) → H 2 O ( g) Δ H vap = 40.7 kJ/mol H 2 O ( g) → H 2 O ( l) Δ H cond = − 40.7 kJ/mol. Other substances have different values for their molar heats of fusion and vaporization; these substances are ... WebEvaporation: When the temperature raises high enough, the water particles begin to move faster and gain more kinetic energy. As they move faster, the particles spread out in all directions. This spreading converts the water into a gas, or water vapor.

WebIt has a high heat of vaporization. This means that more energy is needed to evaporate 1g of water than many other liquids. How is water's high heat of vaporization important … WebWater’s high heat capacity is a property caused by hydrogen bonding among water molecules. When heat is absorbed, hydrogen bonds are broken and water molecules can move freely. When the temperature of water decreases, the hydrogen bonds are formed and release a considerable amount of energy.
