WebMar 4, 2024 · Before looking at a bunch of evaporation examples, it’s important to have a clear understanding of what evaporation is. Evaporation happens when liquids change into gas. It is part of the water cycle. One common example of evaporation is the steam rising from a hot cup of coffee. This heat rising out of the cup helps the coffee to cool down. As we know that, when liquids are cooled, the freezing of a substance takes place. This is because when the temperature is decreased, it means that we are extracting heat from the particles of a substance. As the heat energy is removed from particles, their kinetic energy decreases. This decrease in kinetic energy, in … See more The nature of the intermolecular forces of a liquid directly affects the freezing point of a substance. For instance, when the intermolecular forces of attraction between the particles of a liquid are strong, then its freezing point will be … See more The theory states that the melting point and the freezing point of a substance have to be the same. This applies to the majority of … See more WebApr 9, 2024 · These examples could be written as chemical reactions, but are more generally considered to be endothermic or heat-absorbing processes: Melting ice cubes Melting solid salts stimulus check for high gas prices
