The water rose in the beaker because as the candle burned, it consumed oxygen in the air inside the beaker. This created a partial vacuum, causing the water to be pushed up into the beaker due to the air pressure outside.
The gas trapped in the flask when it is upside-down in the sink of cold water is likely water vapor that has condensed from the surrounding air. As the air inside the flask cools, the water vapor condenses into liquid water, creating a partial vacuum that prevents water from entering the container.
The significant force that attracts water molecules to each other is hydrogen bonding. Water molecules are polar, with a partial positive charge on the hydrogen atoms and a partial negative charge on the oxygen atom. These opposite charges create electrostatic attractions that result in the formation of hydrogen bonds between water molecules.
A deep vacuum can pull out air, water vapor, volatile oils, and other gases from a system. This helps to create a controlled environment with lower pressure, allowing for more effective processes like degassing, drying, or distillation.
located near the oxygen atom and the positive portion located near the hydrogen atoms. This creates a partial positive charge on hydrogen and a partial negative charge on oxygen, making water a polar molecule.
A rubber aspirator sucks up liquid into the pipette.
The freezing point of water decreases as the pressure decreases in a vacuum. At very low pressures, water can freeze at temperatures below 0°C due to reduced atmospheric pressure. The exact temperature at which water will freeze in a partial vacuum depends on the level of vacuum present.
The purpose of the vacuum in the fresh water generator it can make a 50 degrees Celsius boil the water that's why they create a

If an object is in a space it is not a vacuum. No true vacuum exists. I will adress your question assuming a partial vacuum, and assuming the objects will not expand/ be pulled apart by suction forces. The objects will not be able to transfer heat energy through convection and therefor will remain at the same temperature unless they touch, or radiate heat, or are hit by radiation.
That's not true. You can easily pump water higher than 12 meters providing you push it upwards from below. What you can't do is SUCK water upwards by more than 12 meters. The reason for that is that when you 'suck' water upwards, you're really creating a partial vacuum above the water and letting air pressure push the water up the pipe. But the weight of a column of 12 meters of water is more than the amount of air pressure there is to force it upwards, so a partial vacuum forms above 12 meters and the water simply won't move higher than that.
when you contract your diaphram, or the lung muscle, your lungs become somewhat empty. this is called a partial vacuum. this is something that air, water, anything that can go in try to fill. the lungs, now a vacuum, pull stuff, supposed to be air!,into the lungs.
The water molecule has a partial negative and partial positive charge because it is a polar molecule. Electrostatic attraction between the partial negative and partial positive molecules gives the water molecule its partial charge.
To find the partial pressure of water vapor in the vessel, subtract the partial pressure of N2 from the total pressure: Partial pressure of water vapor = Total pressure - Partial pressure of N2 = 2.015 ATM - 1.908 ATM = 0.107 ATM.
A suction Cup will trap air behind itself which causes a partial vacuum. The negative pressure of trapped air or water causes it to keep in contact with the surface it is against.

It will create a vacuum inside which reduces the time for water to boil and will utimately lead to bursting of the Jar due to pressure inside.
