Why does temperature remain constant during boiling of a liquid?
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 the temperature of a melting solid remain constant?
The 'temperature of a substance' remains constant during its melting and boiling point because the change in any state of matter as n solid to liquid or the liquid to a gas involves crossing the 'latent heat of fusion' which causes a change in the intermolecular spacing of the molecules in the substance.
Why does temperature remain constant during melting and condensation?
The temperatures remain constant as there is no change to the kinetic energy of molecules but only a decrease in the potential energy (i.e greater forces of attraction between molecules when the phase changes). Hence, all the energy loss is to decrease potential energy, resulting in constant temperature.
Why does the temperature remain unchanged until the entire solid changes into liquid even if we are heating the solid?
The temperature remains unchanged until the entire solid changes into liquid even if we are heating the solid; it is because the heat is used up by the molecules in overcoming the forces of attraction while state of matter is changing from solid to liquid.
Is temperature constant during condensation?
Condensation, deposition of a liquid or a solid from its vapour, generally upon a surface that is cooler than the adjacent gas. ... Heat is released when a vapour condenses. Unless this heat is removed, the surface temperature will increase until it is equal to that of the surrounding vapour.
Why does the temperature of a substance remain constant at its boiling point?
This will usually cause its temperature to rise. At the melting point, however, the heat causes the substance to melt, an energy requiring transition. As the heat is all going into melting the substance, its temperature does not rise. Similarly at the boiling point the heat goes into vaporizing the substance, rather than further heating it.
What happens to the temperature during melting and boiling?
Temperature remains constant during melting and boiling. when melting the temperature given aslantent heat or hidden heat.During melting of ice there is conversation of state so the hidden heat is used for phase transition. when boiling the same thing happens at the boiling point.
Why does temperature remain constant during a phase change?
Why Temperature Remains Constant during a Phase Change. That’s why the graph in the figure levels off in the middle — the ice is melting. You need heat to make the ice change phase to water, so even though the stove adds heat, the temperature of the ice doesn’t change as it melts.
What causes the temperature of a substance to change?
Temperature change is caused by sensible heat. The heat required to melt or freeze 1kg of substance at constant temperature and pressure is called as the latent heat of fusion. The heat required to vaporize or condense 1kg of a substance at constant temperature and pressure is called as the latent heat of vaporization.
