Evaporation occur at any temperature.
Boiling occur at 100 oC.
Yes, that is partially true. While water is being heated, once its temperature reaches boiling, the water will remain at boiling until all of the water boils away. So, Yes, it does turn to gas, but, No, it doesn't turn to gas all at once. Prior to reaching boiling, the water would have been evaporating at a slower rate. The only thing magical about the boiling point is that is the temperature where the pressure of the evaporating water equals atmospheric pressure.
Boiling and evaporation are physical changes.
Dissolving any salt into water will raise the boiling point.
The boiling point of sea water is higher compared with pure water. Temperature remain constant during boiling.
Evaporation is the process of turning liquid into a gas. Examples of these are the evaporation of water when it is boiled and the evaporation of alcohol at room temperature.
If you add energy to a boiling liquid, it will just boil faster, but the temperature will remain the same, at the boiling point. All the energy goes into phase change, not heating.
If enough energy is absorbed by liquid water, it will eventually reach its boiling point and start evaporating into steam. This process is known as boiling and the water will undergo a phase change from liquid to gas.
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.

The evaporating point of matter refers to the temperature at which a substance transitions from its liquid state to a gas. It is also known as the boiling point for liquids with a defined melting point.
heat whatever you are evaporating to a temperature above its boiling point. for water you must heat it to 100 degrees C
Boiling and evaporation are physical changes.
The purity of water can be tasted by boiling it and marking the exact temperature it evaporates. Evaporating below 100 degrees Celsius will mean that there are impurities.
Dissolving any salt into water will raise the boiling point.
It is the sound of the water and oils evaporating out of the onions as the oil in which they are being cooked is at a higher temperature than the boiling point of water (100 degrees C)
depends on air pressure, if you remove air from a container with water in it it can boil at room temp boiling point is the temperature at which water boils and i believe it is also the evaporating point so 100f*
The temperature of boiling water at sea level is 100 The temperature of boiling water at sea level is 211.149°F.
