Heat of Vaporization for water = 540 Cal/g
when the temprature is hot the substance will evaporate( the person that wrote this before is a dummy)
Water requires a lot of energy to raise its structure and to evaporate.
Heat It Up And Measure The Temperature. Are you serious? How does it evaporate not how you know it evaporates. The soda molecules have more KE or Kinetic energy, energy of motion. The molecules tend to break apart and fly apart.
The amount of energy needed to vaporize 175 g of water depends on the temperature of the water. However, we shall assume it is 100 degrees C. We multiply 175 by 539 and get 94,325 calories. (Notice the small c). We could express it as 94 Calories if we were talking about the stuff on your dining room table.
Water temperature tells you how cold or hot the water is. If the water is hot, the heat indicates the kinetic energy of the water.
These energy sources are the movement of water molecules and the temperature.
The water will slowly evaporate on its own at room temperature, but boiling temperature will do it much faster!
The surface molecules of the water will evaporate. As the kinetic energy increases the water molecules become more free, which causes the water to evaporate.
The needed energy at 100 oC is 48751 MJ.
Liquid water evaporates due to high temperature. Sun's energy help it to evaporate.
Water does not evaporate instantly at a specific temperature. Evaporation is a gradual process that occurs as water molecules gain enough energy to escape into the air. The rate of evaporation increases with higher temperatures, but there is no specific temperature at which water evaporates instantly.
The kinetic energy of water molecules is lower at a low temperature.
Molecules have kinetic energy at any temperature.
You need the amount of water, the temperature of the water, and the desired temperature.
The energy of water molecules increase by a temperature increase and some molecules at the surface can escape in the atmosphere. But water is evaporated at any temperature.
The energy required for water to evaporate from a puddle is called latent heat of vaporization. This energy is needed to break the intermolecular bonds between water molecules so that they can escape into the atmosphere as vapor.
When water molecules at the surface gain sufficient energy they can escape in the atmosphere. Evaporation (not vaporization) occur at any temperature; but a higher temperature increase the rate of evaporation. The energy of water molecules increase by a temperature increase.
