During the boiling of water the temperature stays constant while heat is supplied continuously . It is because the heat provided by the water particles is consumed, and this heat increases their kinetic energy.
When water boils its temperature remains the same or not?
The correct answer is remains constant . When water is boiled, its temperature does not change until it has completely changed into the vapour state. This is because the heat which is supplied is used in changing the state by overcoming the forces of attraction between the water molecules.
Why the temperature of boiling water does not change?
The heat which we supply to water during boiling is used to overcome these forces of attraction between the particles so that they become totally free and change into a gas. This latent heat does not increase the kinetic energy of water particles and hence no rise in temperature takes place during the boiling of water.
Why does the temperature of boiling water remain the same as long as the heating and boiling continue?
The temperature remains constant during boiling of water even though heat is supplied constantly because all the heat energy provided is used up in changing the state of water from liquid to gaseous water vapour.
When water boils its temperature a remains the same B first increases and then decreases C decreases D increases?
So, during phase change there is no increase or decrease in temperature and the heat supplies is use as latent heat of vaporization. Option (C) is correct. Therefore, the temperature remains same when water boils.
What happens to temperature when water boils?
The answer has to do with boiling water. Go ask some people on the street about the boiling temperature of water. Some might say 212°F or even better 100°C—but that’s not always true. As you increase your altitude above sea level, the boiling point of water decreases by about 1°F for every 500 feet increase.
Why does temperature remain constant when water boils?
When boiling occurs, the more energetic molecules change to a gas, spread out, and form bubbles . ... In addition, gas molecules leaving the liquid remove thermal energy from the liquid. Therefore the temperature of the liquid remains constant during boiling.
Why does boiling water stay at 100 degrees?
The answer is the water reaches its boiling point temperature and stays there . ... If you boil water at a higher pressure (below sea level, for example), the boiling point would be higher than 100 °C . At a lower pressure (like in the mountains), the boiling point is a lower temperature.
What is the boiling temperature of water?
For example, water boils at 100 °C (212 °F) at sea level, but at 93.4 °C (200.1 °F) at 1,905 metres (6,250 ft) altitude. For a given pressure, different liquids will boil at different temperatures.
At what temperature water must have started boiling?
D. The simple answer to this question is that the boiling point of water is 100 °C or 212 °F at 1 atmosphere of pressure (sea level).
When you boil water Why does the level of liquid decrease?
when you boil water, you convert it into water vapor, which leaves the pot and mixes with the atmosphere. If you boil the pot long enough, eventually all the water in it is converted to vapor and leaves. the pot is then empty.
Where did the water go after boiling?
Temperature, of course, affects how quickly evaporation happens. Boiling-hot water will evaporate quickly as steam. Evaporation is the opposite of condensation, the process of water vapor turning into liquid water. Boiling water evaporates into thin air .
What produces more severe burns boiling water or steam?
– Now, as water is in a gaseous state in steam, it can be given further heat and its temperature will increase, so steam always has higher temperatures than boiling water. Hence we can say that steam produces more severe burns than boiling water.
What increases the rate of evaporation?
Effect of Temperature: Evaporation increases with the increase in temperature as more molecules get kinetic energy to convert into vapor. When the water is heated, the water molecules tend to move rapidly. This makes the molecules escape faster.
Which solution will boil at constant temperature?
The solution which boil at constant temperature like a pure liquid and possess same composition in liquid as well as vapour state are called azeotropes . The components of azetropes cannot be separated by fractional distillation. Only non-ideal solutions form azeotropes.
Does the temperature of liquid increases further when it starts boiling?
Does the temperature of liquid increase further when it starts boiling ? No , it does not because the energy now supplied is used up as latent heat of vaporisation only.
