Web1 de fev. de 2024 · Water also has an exceptionally high heat of vaporization. Vaporization occurs when a liquid changes to a gas, which makes it an endothermic reaction. Water's heat of vaporization is 41 kJ/mol. Vapor pressure is inversely related to intermolecular forces, so those with stronger intermolecular forces have a lower vapor … WebWater is converted from its liquid form to steam when the heat of vaporization is reached. Since sweat is made mostly of water, the evaporating water absorbs excess body heat, which is released into the atmosphere. This is known as evaporative cooling. Water has …

Water has the second highest specific heat capacity of all known substances. Ammonia has the highest specific heat. Water also has a high heat of vaporization (40.65 kJ·mol−1). The high specific heat and heat of vaporization result from the high degree of … Web8 de set. de 2024 · Water has a physical property called the "heat of vaporization," which is the amount of heat required to vaporize water. The heat of vaporization of water is 540 calories/gram, or 2,260 kilojoules/kilogram. That is a lot more energy than is needed to convert water to ice (the latent heat of fusion), which is 80 calories/gram. philippine airlines financial reports
