Why the temperature does remain constant when a liquid starts changing to vapours?
Because that temperature is needed to change its state.i.e.from solid to liquid.Transition of state can also occurs but not with all.
Answer:
The temperature of a liquid will fall as it evaporates as the heat heaves with the evaporated material. This is why sweating is a mechanism to cool the body or why a cup of hot coffee cools when open to the air.
As to the why, the most active fastest molecules are the ones that can break away from the fluid to disappear into the atmosphere. These contain the majority of the liquids heat. As they are removed the remaining molecules are cooler and the temperature of the liquid goes down.

What is dynamic equilibrium Describe what is happening to the liquid and vapor at the boundary of a liquid that is in dynamic equilibrium Is the overall balance of liquid and vapor changing?
1. Dynamic equilibrium is when the rate of vapour and liquid being produced has stabilized, and stopped changing. It's called dynamic equilibrium because the liquid hasn't stopped changing into vapour, and the vapour hasn't stopped changing into liquid, but the rates of these two changes has stabilized so that there is a constant amount of liquid and vapour present.2. At the boundary of the liquid, particles with sufficient energy break away from the liquid and become vapours, and vapour molecules with low energy, or those that make contact with the surface of the liquid, become bonded to the liquid. There is a constant exchange of particles, hence dynamicequilibrium3. No, the overall balance of liquid is constant, hence equilibrium.
When heat is added to a liquid at the boiling temperature it converts the liquid into a gas at the same temperature because?
The additional heat, called "enthalpy" completes the phase change, by changing the arrangement of the molecules in the existing environment, not the temperature. The energy must be removed from a gas to cause condensation into liquid, and from a liquid to cause solidification (freezing). Conversely, it is added when changing a solid to a liquid or a liquid to a gas. At a certain temperature (critical temperature), the process happens spontaneously because the phase boundary disappears.
When will liquid alcohol change to vapor?
Any form of liquid alcohol will change to vapor when its temperature reaches the boiling point (different for each type of alcohol).Alcohol (ethyl alcohol) is a volatile liquid and changes in to vapours at every temperature although its boiling point is 78.5 Celsius.
What happens to the temperature of boiling water when heat is added to the boiling water?
If you add energy to a boiling liquid, it will just boil faster, but the temperature will remain the same, at the boiling point. All the energy goes into phase change, not heating.
When solid changes into liquid?
Solids changing to liquids are melting Liquids changing to solids are freezing Solids changing to gas are subliming Liquids changing to gas are boiling Gases changing to liquids are condensing.
What is the gaseous form of a substance which exists as a liquid at a room temperature known as?
You think to vapours of a liquid.
Can a liquid and gas together be at same temperature?
Yes, at boiling point and in a close container a liquid and its vapours coexist.

Why does temperature remain constant at 0 celsius?
At 0 degrees Celsius, water is changing phase from a liquid to a solid, or melting at this temperature. As the molecules rearrange, it absorbs heat energy from the surroundings to break intermolecular bonds, keeping the temperature constant until all the liquid has transformed into solid.
Boiling liquid maintains a constant temperature?
The boiling point temperature remains constant because liquids evaporate at this point. If the temperature drops the liquid will no longer boil. At a higher temperature the vapor becomes hotter, not the liquid.
Why liquid boils at constant temperature at a given temperature?
Yes.
Why does temperature stop changing while a liquid freezes?
During freezing, the energy from the liquid is used to break the intermolecular bonds and convert the liquid into a solid state. This process requires energy, which is taken from the surrounding environment causing the temperature to stabilize until all the liquid has solidified. The temperature remains constant until the phase change from liquid to solid is complete.
When a liquid is changing to a solid what is it?
freezing temperature
The temperature at which a gas starts changing into a liquid is called?
Its condensation temperature.
Changing solid into liquid by increasing temperature?
Ice
What is the difference between water and water vapours?
water is a liquid but water vapours is steam... when we boil water it will turn into steam which is called water vapours...
What is the amount of heat to change liquid into solid at constant temperature?
To change a liquid into solid at constant temperature, an amount of heat is released equal to the latent heat of that liquid. For water it is about 80 calories per gram.
