Your question: Why does temperature remain constant during boiling?

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 temperature remain constant at boiling point?

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. … Therefore, the temperature stays constant only though heat is continually supplied to the water.

Why does the temperature stay constant during melting boiling?

The extra heat supplied to the boiling water is used in the vaporization of a liquid, which is known as the latent heat of vaporization. That’s why the temperature of a substance remains constant during its melting or boiling.

Why does temperature remain constant at 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 temperature remain constant when water boils?

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 the temperature remain constant during the melting of ice?

The temperature remains constant during the melting of ice because the heat supplied to the ice is used for changing the solid ice to liquid. The latent heat absorbed by the solid ice is used for breaking the inter-molecular force rather than increasing the temperature of ice.

Why does temperature not change during melting a solid even if it is being heated constantly?

Energy is required to melt a solid because the cohesive bonds between the molecules in the solid must be broken apart so that the molecules can move around at comparable kinetic energies; thus, there is no rise in temperature. … There is no temperature change until a phase change is complete.

Why the temperature of all body remain constant at room temperature?

All bodies radiate as well as absorb radiation at room temperature, but their rate of emission and rate of absorption is the same, hence their temperature remains constant.
