Yes, even when it is in the ice phase, the ice will sublime directly into water vapour without passing through the liquid phase. In a bulk volume of water, the molecules individually have different energies, and the hotter ones; which have a higher energy and thus velocity; will escape first. Thus puddles evaporate, and the oceans evaporate to form airborne moisture.
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.
yes, either by reducing the temperature until the solution is beyond saturated, causing some NAOH to crystallise, or by doing the opposite and evaporating off the water (the first will require the crystals to be filtered out)
Yes, you can obtain pure calcium nitrate crystals by evaporating the solution to dryness. As the water evaporates, calcium nitrate will start to crystallize out of the solution. To ensure purity, it is important to start with a pure calcium nitrate solution and use distilled water for evaporation.
The specific property of water evaporating is called evaporation. During this process, water changes from a liquid state to a gaseous state due to heating.

Evaporation occur at any temperature.Boiling occur at 100 oC.
This depends on the temperature in your area.
Decreasing the temperature, evaporating water, or adding more salt.
Lower temperature and the counter-effect of condensation.
yes because temperature is factor that starts the water cycle by evaporating the water so it can become a rain cloud and do the rest of the water cycle
Water is evaporated at any temperature because the movement of water molecules is continuous and some molecules at the surface can escape as a gas.
The temperature must be increased up to 100 oC.
a fall in the temperature of the liquids known as the cooling effect ,accompanies evaporation
Examples: temperature, humidity of the atmosphere, water area exposes to atmosphere, etc.
The density of water increase, also the humidity of the atmosphere; the temperature decrease.
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.
In a given liquid, the atoms or molecules which are moving the fastest, and hence have the highest temperature, are the ones that are most likely to leave the liquid and evaporate. The atoms or molecules that they leave behind will therefore be cooler. Examples: evaporating water evaporating alcohol evaporating liquid nitrogen evaporating glycerol evaporating liquid helium evaporating acetone.
