What else can I help you with?
Does water inside a vacuum boil at a higher or lower temperature than it does under normal pressures?
It boils at a lower temperature because of the less energy needed.
How do gas law applied on vacuum evaporator?
Gas laws are not directly applied in vacuum evaporation because the process occurs under reduced pressure, typically in a vacuum chamber. The decrease in pressure lowers the boiling point of the liquid being evaporated. This allows the substance to change from liquid to gas phase at a lower temperature without the need for specific gas law calculations.
How can you boil water at a temperature lower than 100 celsiuse?
Place the container of water in a vacuum & it should start to boil at room temperature.
Which fluid evaporated more quickly water or ethanol explain why?
Ethanol is evaporated faster because the enthalpy of vaporization is lower.
What point does liquid evaporate quickest?
Lower the pressure and higher the temperature, faster is the evaporation. Therefore, in vacuum and at the temperature just below decomposition point of the substance, its evaporation shall be fastest.
At what temperature does water evaporate with a 28 inch Vacuum?
Water will evaporate at a lower temperature than its normal boiling point when exposed to a 28-inch vacuum. The exact temperature at which water will start to evaporate will depend on the specific vacuum level and conditions, but it will be below 100 degrees Celsius.
How can a researcher ensure that water is being used for an experiment that will vaporize at a point lower then normal temperature?
The researcher can lower the pressure inside the experimental setup to decrease the boiling point of water, allowing it to vaporize at a lower temperature. This can be achieved using a vacuum pump to create a vacuum environment. It's also important to monitor the temperature and pressure conditions during the experiment to ensure accurate results.
Why higher boiling hydrocarbonates are distilled under vacuum condition?
because they decompose at higher temperature.. under vacuum they can be boiled at lower temperature than their boiling point

What is the lower layer temperature?
The lower layer temperature typically refers to the temperature of the lower atmosphere, which can vary depending on location, time of day, and weather conditions. It is important for understanding weather patterns and climate dynamics.
Why does evaporated salt water look different from before it was separated?
The evaporated water from salt water has a lower density.
What are two ways air can become saturated with water vapor?
To saturate the air with water vapor, you can lower the temperature to it's dew point, and leave out water to be evaporated.
Which fluid evaporated more quickly water or ethanol explain why?
Ethanol is evaporated faster because the enthalpy of vaporization is lower.
What conditions are needed for liquid water?
Temperature higher than freezing and lower than boiling.
Ether at room temperature is placed in a flask connected by a rubber tube to a vacuum pump the pump is turned on and the ether begins to boil why?
Because the pressure of the atmosphere in the flask is lowered by the vacuum; a liquid will reach it's boiling point when the pressure of the atmosphere is equal to or less than the vapor pressure of the liquid.
