What does the lowered pressure do to the boiling temperature of water?
Lowering the pressure decreases the boiling point of water. This is because at lower pressures, the molecules in the water require less energy to escape into the vapor phase, thus resulting in a lower boiling temperature.
Does salt lower the boiling point?
Yes, Salt also lowers the freezing point of water, and lowers the boiling point of water. Add salt to a boiling pot of water and it immediately boils faster/harder at the location that the Salt hit the water.
Why is temperature of boiling water cannot be measured using an alcohol thermometer?
Alcohol thermometers are not suitable for measuring the temperature of boiling water because alcohol has a lower boiling point than water. The alcohol inside the thermometer would evaporate before reaching the temperature of boiling water, therefore providing an inaccurate reading.
If frozen vegetables are added to a pot of boiling water in what direction will heat energy flow?
When frozen vegetables are added to a pot of boiling water, heat energy will flow from the boiling water to the frozen vegetables. This occurs because heat transfers from areas of higher temperature (the boiling water) to areas of lower temperature (the frozen vegetables) until thermal equilibrium is reached. As a result, the frozen vegetables will gradually thaw and cook as they absorb heat from the water.
Can boiling water will stay at the same temperature when you lower the heat under it but keep it boiling?
Yes
Goes salt lower boiling temperature of water?
No, salt does not lower the boiling temperature of water. In fact, adding salt to water increases its boiling point. This occurs because the salt disrupts the formation of hydrogen bonds between water molecules, making it harder for them to escape as vapor.
How does pressure affect the temperature at which water boils?
There is a direct relationship between the temperature at which water boils and the air pressure on it. Higher pressure, higher boiling point. Lower pressure, lower boiling point.
Why doesn't the temperature of boiling water change as heat continues to be added?
The temperature of boiling water remains constant at the boiling point (100°C at sea level) because the added heat energy is used to convert the liquid water into water vapor, rather than increasing the temperature. This phase change absorbs heat without affecting the temperature.
Why does water boil at a lower temperature in denver than in dallas?
Water boils at a lower temperature in Denver compared to Dallas due to the difference in elevation. Denver is at a higher altitude, which means the air pressure is lower, resulting in water boiling at a lower temperature. This is because lower air pressure reduces the boiling point of water.
Why did hot water stop boiling immediately for a short while when something is dropped in it?
Because the temperature of the object is lower than the temperature of the water. When the object is sunk, the water temperature drops below boiling.
Does boiling water effectively remove chlorine?
Yes, boiling water can effectively remove chlorine as it evaporates at a lower temperature than water.
Does Epsom salt increase the temperature of boiling water?
No, Epsom salt does not increase the temperature of boiling water. However, it can help to increase buoyancy and reduce the cooking time of certain vegetables when added to boiling water.
