Evaporation occur at any temperature.
The boiling point of water is 100 oC at 760 mm Hg.
Water starts to evaporate as soon as it reaches its boiling point of 100 degrees Celsius (212 degrees Fahrenheit). At this temperature, the kinetic energy of the water molecules increases enough for them to overcome the intermolecular forces holding them together, transitioning from liquid to gas state.
There are more water vapor molecules above a beaker of water at its boiling point because the higher temperature causes more water molecules to evaporate into the air. This results in a higher concentration of water vapor over the boiling water compared to room temperature water.
The temperature of boiled water at sea level is typically around 100 degrees Celsius (212 degrees Fahrenheit). However, if you are referring to water that has already been brought to a boil and is kept boiling for 1 minute, its temperature will remain at approximately 100 degrees Celsius until the water starts to evaporate. Factors like altitude can affect this boiling point, with lower pressures leading to lower boiling temperatures.
You boil a substance to evaporate the liquid.
There is no such temperature to start evaporating. Even in the room temperature or in a refrigerator, water does evaporate. When a particular water molecule absorbs adequate energy (let's say from heat), there will be a phasechange in that molecule from liquid to gas, and it's called evaporation.
When water is heated steadily, its temperature will stop rising when it reaches its boiling point and starts to convert into vapor. This process is known as boiling and occurs at a specific temperature depending on air pressure.
The boiling point of water is 100 oC at 760 mm Hg.
When boiling water to make hot chocolate, the water molecules gain energy and begin to move faster, causing the water to increase in temperature. Eventually, the water reaches its boiling point, at which it starts to evaporate and turn into water vapor.
Water starts to evaporate as soon as it reaches its boiling point of 100 degrees Celsius (212 degrees Fahrenheit). At this temperature, the kinetic energy of the water molecules increases enough for them to overcome the intermolecular forces holding them together, transitioning from liquid to gas state.
A high temperature favors evaporation.
No, salt does not evaporate in boiling water. When water boils, it turns into steam, leaving behind the salt in the water. Salt does not have a low enough boiling point to evaporate along with the water.
The physical state change from liquid to gas usually occurs at boiling. However water can evaporate at room temperature. Evaporation is not boiling, it is a process by which surface molecules of water are escaping into the air.
The water will slowly evaporate on its own at room temperature, but boiling temperature will do it much faster!
Water can evaporate without boiling when it reaches a certain temperature called the "boiling point." This happens when the water molecules gain enough energy to break free from the liquid and turn into vapor. Evaporation can occur at any temperature, not just the boiling point, as long as there is enough heat energy present to allow the water molecules to escape into the air.
Evaporation (not vaporization) occur at any temperature; a higher temperature increase the rate of evaporation.
It rose to 100 degrees Celsius. The water starts to evaporate?
