Why the temperature of boiling water does not rise even though heat is being given continuously?

The temperature of boiling water does not rise even though heat is being supplied continuously because the heat which is supplied is used as latent heat of vaporization to convert boiling water into steam and it does not rises the temperature of boiling water .

Why the temperature of boiling water does not rise even though heat is given continuously?

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 mountain is warmer than the surrounding air and it causes the air to rise. Why does the temperature of boiling water remain the same as long as the heating and boiling continue? … Water or any liquid will boil when the pressure of molecules is equal to the pressure over the surface.

Does the temperature of water rise continuously if heat is supplied continuously?

Answer Expert Verified

1) the temperature of water does not rise continuously if heat is supplied to it. 2) when it reaches its boiling point (100 deg celcius) the temperature remains constant for some time. 3) because the supplied heat energy will be used for breaking bonds and impurities present in it.

Why does the temperature of H2O not increase when it is boiling explain your answer by drawing a heating cooling curve for water?

Why does the temperature of H2O not increase when it is melting? Explain your answer by drawing a heating/cooling curve for water. The temperature does not increase because all the energy is going towards breaking the intermolecular forces.

When water is heated without rise of temperature it consumes?

When water is heated, latent heat of vaporisation is consumed to overcome the intermolecular forces of attraction at a constant temperature.

Why is the constant temperature of boiling water on a hot stove evidence that boiling is a cooling process?

It gives kinetic energy to molecules and water molecules start moving faster and converted to vapor phase with rise in a temperature to boiling point. The atmospheric pressure, here allows the vapors to condense again and change into water (liquid phase). This is the evidence that the boiling is a cooling process.

What happened to the level of water after boiling for 10 minutes?

Answer. Answer: Boiling is the procedure by which a fluid transforms into gas when it is warmed to its breaking point. … After 10 minutes of boiling, maximum water is evaporated.

Why does boiling water stay at 100 degrees?

The vapor pressure increases with temperature, because at higher temperature the molecules are moving faster and more able to overcome the attractive intermolecular forces that tend to bind them together. … At standard atmospheric pressure (1 atmosphere = 0.101325 MPa), water boils at approximately 100 degrees Celsius.

Why does temperature remain constant during melting and boiling?

The extra heat supplied is used in the melting of ice which is called the latent heat of fusion. Similarly, when a liquid starts boiling the temperature of the liquid does not change instead of a continuous supply of heat. … That’s why the temperature of a substance remains constant during its melting or boiling.

Does water boil same temperature everywhere?

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.

When water boils its temperature remains the same?

Answer. When water boils its temperature remains constant. It is because of latent heat. The heat given to the system is spared for phase transition of water.

When heat is constantly supplied by a burner to boiling water then the temperature of water during preparation?

Temperature of the water during vaporisation does not change at all because the heat is used in overcoming particle-particle attraction forces, which in turn keeps the temperature constant.

Why does boiling take longer than melting?

Answer. It takes longer to boil water than to melt ice because of the difference in the amount of heat required to overcome the forces of attraction by keeping the temperature constant during this time. … This is the reason it takes longer in boiling than in melting.

What is heating curve?

A heating curve graphically represents the phase transitions that a substance undergoes as heat is added to it. The plateaus on the curve mark the phase changes. The temperature remains constant during these phase transitions.

Which phase is the easiest to heat?

Solid to a Liquid and Back to a Solid

You need some energy. Heat is probably the easiest energy you can use to change your physical state. The atoms in a liquid have more energy than the atoms in a solid. There is a special temperature for every substance called the melting point.
