The main influences over the heat of vaporization are the interactions between molecules in a solution. The vaporization is the opposite process of condensation. The high boiling point of water (similar sized molecules are normally gases at room temperature) is also due to its ability to form hydrogen bonds. This is another unique property that allows water to maintain its temperature. So, a high value means that it takes MORE energy to raise (or lower) its temperature. Why is the heat of vaporization higher than the heat of vaporization for water?

Boiling is an unnatural process where the liquid gets heated up and vaporized due to continuous heating of the liquid. The high heat of vaporization refers to the amount of heat energy that we need in order to be able to change one gram of water into gas. The required increase in internal energy can be described as the energy needed to break the intermolecular interactions in the liquid. The reason why these two processes have to be distinguished in the case of gases can be seen if the gas is heated and the temperature increase is observed in each case. This same concept can be expanded to a world-wide scale. Climate change, and global warming specifically, are adding lots of heat to the atmosphere. Because of the high heat of vaporization, evaporation of water has a pronounced cooling effect and condensation has a warming effect ( Kramer, 1983, p. 8 ).

Substances with high vapor pressures are said to be volatile - that is . Water has a high heat of vaporization because hydrogen bonds form readily between the oxygen of one molecule and the hydrogens of other molecules. To get water to vaporize, you must increase the temperature to make the molecules move faster. The heat from the sun makes the water molecules move faster and faster, until they move so fast they escape as a gas. It is expressed as kg/mol or kJ/kg. Answer: Steam produces more severe burns than boiling water even though both are at 100oC because steam contains more heat, in the form of latent heat, than boiling water.

This cold gas, bubbles up, and cools down the water vapour, turning it into fog (condensation). It is defined as the heat required to change one mole of liquid at its boiling point under standard atmospheric pressure. Water has a relatively high specific heat, or heat capacity, meaning it can absorb a lot of heat before its temperature rises. This expansion will lead to much of the flooding that is currently estimated by climate scientists. molecule. As a liquid, water has more directions to move and to absorb the heat applied to it. times that required to raise liquid water's temp one degree.). These particles move into a gaseous phase as the bond between them and the rest of the liquid breaks. This is because of the large separation of the particles in the gas state. We and our partners use data for Personalised ads and content, ad and content measurement, audience insights and product development. The heat of vaporization diminishes with increasing pressure, while the boiling point increases.
