Your question: Why doesn’t the water at the bottom of a geyser boil when it is at 100 C?

What happens to the water pressure at the bottom of a geyser when some of the water above gushes out what is the result?

What happens to the water pressure at the bottom of a geyser when some of the water above gushes on? As water gushed out, the pressure on the remaining water is reduced; the water boils rapidly and erupts with great force. Afterwards, the geyser refills and repeats the cycle.

Why does the temperature of boiling water remain the same as long as the heating and boiling continue?

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.

What evidence can you cite for the claim that water can boil at a temperature of 0 C?

Evidence that water can boil at a temperature of 0°C? Ice will form in boiling water in a vacuum chamber. Pressure is greatly reduced, water starts to boil. Continued boiling results in lowered temperature, and lower boiling point.

Why does the boiling temperature of water decrease when the water is under reduced pressure such as at a higher altitude?

At elevated altitudes, any cooking that involves boiling or steaming generally requires compensation for lower temperatures because the boiling point of water is lower at higher altitudes due to the decreased atmospheric pressure. The effect starts to become relevant at altitudes above approximately 2,000 feet (610 m).

What is difference between evaporation and boiling?

Evaporation is a normal process that occurs when the liquid form changes into the gaseous form; while causing an increase in the pressure or temperature. Boiling is an unnatural process where the liquid gets heated up and vaporized due to continuous heating of the liquid. … Bubbling effect is not visible in evaporation.

Why doesn’t the temperature of water keep changing at the melting point or boiling point as heat continues to be added?

This is because once water reaches the boiling point, extra energy is used to change the state of matter and increase the potential energy instead of the kinetic energy. … At the boiling point, temperature no longer rises with heat added because the energy is once again being used to break intermolecular bonds.

When the water boils why does its temperature remain constant?

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.

Why does the temperature remains unchanged at the boiling point of water?

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. … In addition, gas molecules leaving the liquid remove thermal energy from the liquid. Therefore the temperature of the liquid remains constant during boiling.

Can water boil at 50 degrees?

At higher pressures (such as the pressure generated in a pressure cooker), the temperature must be higher before the vapor pressure reaches the surrounding pressure, so water under pressure boils at a higher temperature.

Temperature (degrees Celsius) Vapor Pressure (MPa)
50 0.012 35
75 0.0386
100 0.1014
150 0.4762

Why is a steam burn more damaging than a burn from boiling water at the same temperature quizlet?

Why is a steam burn more damaging than a burn from boiling water at the same temperature? … Heat is being added, but the temperature is remaining the same. Just like evaporation, higher energy molecules are leaving, and the remaining liquid molecules are slower/cooler.

Does a common electric fan cool the air in a room if not then why is it used in an overly warm room?

Does a common electeric fan cool the air in a room? If not, then why is it used in an overly warm room? A fan does not cool the room but increases the evaporation of perspiration which cools the body.
