Why does the temperature stay constant while the water is boiling even though you are still adding heat?

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.

Why does temperature remain constant during the boiling of water even though heat is being supplied continuously class 9?

As a result, water is converted into gas. This heat energy is called the latent heat of vaporization.

Why doesn’t the temperature change when water boils?

The temperature stays constant because the water molecules that are “hotter” are escaping into the air as fast as they can. The energy being added is literally breaking the hydrogen bonds of the liquid and giving the molecules enough energy to become gas molecules.

Why the temperature of boiling water does not change no matter how much it is heated?

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.

What is the temperature when the water boils answer?

100° C
At sea level, water boils at 100° C (212° F). At higher altitudes the temperature of the boiling point is lower.

What is the temperature when the water boils?

212°F (100°C)
Water/Boiling point

It seems like one of those basic science facts: Water boils at 212 degrees Fahrenheit (100 degrees Celsius), right? Well, not always. It depends on where you’re doing the boiling. In fact, water will boil at about 202 degrees in Denver, due to the lower air pressure at such high elevations.

What is the temperature when water boils?

The boiling point of a liquid varies according to the applied pressure; the normal boiling point is the temperature at which the vapour pressure is equal to the standard sea-level atmospheric pressure (760 mm [29.92 inches] of mercury). At sea level, water boils at 100° C (212° F).

Why does the temperature remain constant during melting and boiling point?

Answer: The temperature of a substance remains constant at its melting and boiling points until all the substance melts or boils because, the heat supplied is continuously used up in changing the state of the substance by overcoming the forces of attraction between the particles.

Why does the temperature of water stay constant physics?

4 Answers. This is because the external pressure is constant (at one atmosphere). If you increase the pressure, e.g. by using a pressure cooker, then the temperature goes up, or likewise if you reduce the pressure the temperature goes down.

Does water boil at different temperatures?

The boiling point of a liquid varies depending upon the surrounding environmental pressure. 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.

Does pure water boil?

Every schoolchild learns that, under standard pressure, pure water always boils at 100 degrees C. Except that it does not. By the late 18th century, pioneering scientists had already discovered great variations in the boiling temperature of water under fixed pressure.
