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 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.
What conditions are gases most soluble in water?
The solubilty of gases in water is increased at lower temperatures and higher pressures.
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 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.
What conditions are needed for liquid water?
Temperature higher than freezing and lower than boiling.
Why does evaporated salt water look different from before it was separated?
The evaporated water from salt water has a lower density.
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.
What will happen if vacuum in surface condenser is very high?
If the vacuum in the surface condenser it very high, it results in higher practical thermal efficiency. It is important for you to keep the temperature to 100 Celsius or lower for it to work properly.
How do you suvee?
Sous-vide ("under vacuum") is a method of cooking where food is sealed in an air-tight bag and cooked for a long period of time at somewhat lower temperature.
How long do you boil green beans to make a vacuum?
You boil them in a pressure cooker at 11 pounds and 240° F. for 25 minutes. You can make a vacuum and seal the jar at a lot lower temperature, but when cooking beans, a consideration that's more important than the vacuum is the concern for botulism. Botulism can actually grow in a vacuum. That's why the temperature, pressure, and cooking time have to be right. There's a great web site about canning beans at the link below.
What conditions are gases most soluble in water?
The solubilty of gases in water is increased at lower temperatures and higher pressures.
