What happened to the boiling water after you removed from the hot plate?

The heat influx stops because you turn off the stove. For a small moment there is enough heat in the vessel to boil some more water, which cools down the water proper and the vessel. Because of the energy used for evaporation the water temperature drops below the boiling point, and the water stops boiling.

Why does water in a vessel starts boiling when the vessel is heated?

Outside water is completely boiled. Outside water(now steam) heats up an infinitesimal amount. Outside water continues to heat up, but also transfers heat to inner vessel. The vessel heats up and the inner water starts boiling.

Why does the amount of water inside the beaker decreases after boiling?

when you boil water, you convert it into water vapor, which leaves the pot and mixes with the atmosphere. If you boil the pot long enough, eventually all the water in it is converted to vapor and leaves. the pot is then empty.

What happens when water is heated in a closed vessel?

Water will not boil but forms a supercritical fluid above its critical temperature.

When water is boiled part of it becomes water vapor which of the following describe the change?

When boiling occurs, the more energetic molecules change to a gas, spread out, and form bubbles. These rise to the surface and enter the atmosphere. It requires energy to change from a liquid to a gas (see enthalpy of vaporization). In addition, gas molecules leaving the liquid remove thermal energy from the liquid.

What type of heat transfer is boiling water?

If you boil water in a kettle, the heat is transferred through convection from the fire to the pot.

What does water become when it boils?

When water is boiled, the heat energy is transferred to the molecules of water, which begin to move more quickly. Eventually, the molecules have too much energy to stay connected as a liquid. When this occurs, they form gaseous molecules of water vapor, which float to the surface as bubbles and travel into the air.

What is transition boiling?

Transition boiling is an intermediate, unstable form of boiling with elements of both types. The boiling point of water is 100 °C or 212 °F but is lower with the decreased atmospheric pressure found at higher altitudes. Boiling water is also used in several cooking methods including boiling, steaming, and poaching.

Why does boiling water decrease?

The boiling point of a liquid is defined as the temperature at which the vapor pressure of the liquid is equal to the external pressure. When the pressure above a liquid is reduced, the vapor pressure needed to induce boiling is also reduced, and the boiling point of the liquid decreases.

Why does water expand when heated?

2.1 A was heated. An increase in temperature caused the water molecules to gain energy and move more rapidly, which resulted in water molecules that are farther apart and an increase in water volume. When water is heated, it expands, or increases in volume.

Does boiling occur in a closed vessel?

No, boiling in the closed vessel does not take place because boiling always occur when the pressure of the liquid becomes equal to the atmospheric pressure. so, when the vessel is closed the vapour pressure inside the container becomes greater than the atmospheric pressure.

Why boiling does not occur in a closed vessel?

Boiling does not occur when liquid is heated in a closed vessel because liquid is not able to vapourise from the surface.
