As water evaporates from the boiling pot,its temperature drops.This results from the fact that water molecules during evaporation extract its latent heat of vapourization from the pot, thereby exerting a cooling effect on it and its content.Regulation of body temperature by sweating is based on this principle. When sweat comes out of its pores, usually in suny days, it evaporates and in the process extract its latent heat of vapourization from the body.This causes the body temperature to decrease.In this way it keeps the body temperature fairly constant.
The temperature remain constant; at boiling temperature the word is boiling not evaporation.
The temperature of the surroundings when water evaporate decrease because water is an endothermic process.
The temperature of the water remain constant.
The temperature decrease because evaporation is an endothermic process and absorb heat.
The only changes of state in pure boiling water is from liquid to gas.
Which is most likely be the temperature of boiling water? 100oC is the boiling point of pure water - when water is boiling, it stays at a constant temperature until all of it is evaporated.
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.
At sea level the normal boiling temperature is 212 °F. As you go up in elevation, the boiling temperature drops.
Pepper has the least effect on the temperature or reaction to boiling water ,As well pepper does not dissolve in boiling water like other grains.
The temperature remain unchanged.
The temperature remain unchanged.
My best guess would be at boiling point, or when water evaporates, which is 100C.
When water is heated, the temperature increases until the boiling point. During the transition from liquid water to gaseous water (steam), the temperature does not change, and the the temperature rises again.
Evaporation occur at any temperature, boiling only at the boiling point - 100 oC at standard pressure.
the water evaporates
It will evaporate at any temperature, as long as the humidity is less than 100%. It does evaporate much faster at higher temperatures though. Technically the boiling point of pure water is 100 degrees C, so that is the temperature at which it becomes gas.
as each molecule of water evaporates it takes heat with it, lowering the temperature of the surrounding water, so it takes time before every molecule evaporates.
When boiling water, the elements do not seperate. The only substance that evaporates is water as 'steam'.
it evaporates with the water
boiling point is a property which depends upon the atmospheric pressure. when vapour pressure of water is equal to external is called its boiling point.. if pressure is equal to atmospheric pressure ,boiling point is 100 degree celcius.
Water evaporates at almost any temperature. However, at higher temperatures, the vapor pressure is higher. It is said to be boiling when the vapor pressure is equal to the atmospheric pressure.
