Why there is no change in temperature in thermometer when boiling water at hundred degree Celsius changes into steam ? pls give me answer fast and atleast of 3 marks.
Answers
Explanation:
the temperature will only remain constant while the heat source is still being applied. The temperature of the water will not exceed 100 degrees because above this the water will no longer be a liquid, it will be in a gaseous state (steam).
At the boiling point all the heat energy is being converted to kinetic energy, causing the particles to move faster, and as they reach the surface they will ‘escape’ the liquid and become gas particles. This will continue until all the particles have left the liquid state.
Answer:
When we provide heat to water , the particles start moving even more faster .At a certain temperature ,the particles are able to break through the forces of attraction of each other . A state is reached when there is a conversion from liquid to steam. This heat energy is being used up in the conversion of state and to overcome the force of attraction . Boiling is a bulk phenomenon .This heat energy is called latent heat of vapourisation .It is defined as the amount of heat energy required to change unit mass of liquid in its vapour form at boling point at atmospheric temperature.
