Does the Temperature of Boiling Water Remain Constant

14 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.

A good source will say when you heat something up energy is used for two things.

. If you boil water at a higher pressure below sea level for example the boiling point would be higher than 100 C. In the case of phase transitions of pure substances the temperature remains constant only if the pressure is kept constant at the same time isobaric process. Increasing the boiling temperature in a pressure cooker.

This is because the external pressure is constant at one atmosphere. Does boiling water stay at 100 degrees. Thats why the temperature of a substance remains constant during its melting or boiling point.

However at 100ºC the partial pressure of the steam in equilibrium with the water rises to one atmosphere and it cant get any higher. Consequently the temperature does not remain constant in this case. This heat is called latent heat of vaporization as it does not increase temperature of either water or the steam.

Temperature is a measure of this and only this. Hence the temperature remains constant as all the heat is used up and no external heat is released or absorbed. Why does temperature remain constant when water is boiling.

Kinetic energy means the speed of the particles. By using a pressure cooker then the temperature goes up or likewise if you. It is due to the latent heat as the heat supplied to increase the temperature of the substance is used up to transform the state of matter of the substance hence the temperature stays constant.

Increase kinetic energy of particles. The temperature of boiling water remains constant even if heat is being supplied because the supplied heat is utilized for producing steam. The extra heat supplied to the boiling water is used in the vaporisation of water which is known as latent heat of vaporisation.

If you increase the pressure eg. So if you raise the temperature above 100ºC the water and vapour cannot be in equilibrium so the water boils continuously in a desperate but hopeless attempt to raise the steam pressure. So temperature speed.

15 What happened to the temperature of the water after it. The answer is the water reaches its boiling point temperature and stays thereAt sea level water boils at 100 C 212 F and freezes at 0 C 32 F. When water boils or freezes during these process its temperature.

Phase of transition of mixtures of substances. 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. Answer 1 of 33.

Therefore all the heat energy provided increases the kinetic energy of the particles and temperature doesnt increase.
