Relation between atmospheric pressure and boiling point?
As atmospheric pressure increase so does the boiling pont, when atmos. pressure decreases so does boiling point. A liquid boils when its vapor pressure equals atmospheric pressure.
How does increasing pressure in a chamber help treat the bends?
Spending time in a barometric chamber (in which the pressure is raised above atmospheric) causes nitrogen bubbles in the blood stream (the cause of the bends) to go back into solution and gives the nitrogen the opportunity to exit the body via the lungs so that it won't come back out of solution when the pressure is lowered.
Why do vapor bubbles not form in water at room temperature and standard pressure?
we know that water bubbles are formed when external pressure becomes equal to the internal pressure so room temperature is 20 digree to 25 digree and internal pressure deos not equal to external pressure at this temperature so it is clear that vapor bubbles deos not formed in water at room temperature and standard pressure where standard pressure is 760 torr.
Do square bubbles exist?
Square bubbles are impossible because the pressure inside the bubble is pressing out equaly. That is why they are spherical.
How bubbles affect how fast does water freezes?
it affects the water because the bubbles have oxygen inside them which causes pressure
Why does water boil when the vapor pressure is equal to atmospheric pressure?
Because while atmospheric pressure is the greater of the two the vapour pressure of the water can not spontaneously form bubbles (ie boil).
How does carbonation effect density?
The air bubbles lower the density of the solution
Can bubbles be square?
The bubbles can never be of square shape for surface tension reasons as well as the reason that the pressure inside the bubble is distributed equally through all directions.
Why do you see bubbles coming out when you open a Pepsi can?
The fluid is saturated or close to saturation with CO2 at the pressure in the bottle before opening, but supersaturated at atmospheric pressure. Bubbles will form (nucleation) on any floating solids or surfaces allowing the CO2 to approach saturation at atmospheric pressure.
Does an air bubble in the water contain atmospheric air or dissolved air?
It is disolved air because it is contained in the water, and is not free air in the atmosphere. Most bubbles in water are carbon dioxide. In a carbonated drink, this carbon dioxide gas that is put in the water (or Coke) under pressure, when the pressure is released the bubbles form. Even in pond water, the bubbles are likely caused by some small animal.
When water in a beaker is heated bubbles come out to the surface why?
When a droper is dipped into water and its bulb is pressed air bubbles seems to occur in water because the dropper was filled with air before it was dipped in water and when we press the bulb air comes out forming air bubbles and the space is filled with water .
Does the boiling temperature of water change with altitude?
The boiling point of a substance is the temperature where the molecules have enough energy to break the inter molecular bonds and form gas bubbles anywhere throughout the liquid. The higher the atmospheric pressure the more energy is required to form the bubbles and, therefore, the higher temperature is required. The boiling point of water varies depending on the weather ie the current atmospheric pressure. The boiling point of water decreases as the altitude increases.
Why do bubbles rising to the surface of the ocean expand?
The deeper the bubbles are in the ocean, the greater the pressure is. As they rise to the surface, the pressure decreases, allowing the bubbles to expand.
Pressure has an effect on boiling point because pressure affects what?
In this case pressure affects things only passively. A liquid boils when it is hot enough so that its vapor pressure equals/exceeds the external atmospheric pressure. At lower temperatures the external prsssure collapses any bubbles that might form.
How and why do air pressure presses downward direction?
Air pressure fills a vacumm of non existing air into a chamber kind of like a balloon when u put air in it creates pressure. Our atmosphere is also like a big balloon, i hope that answers ur question thanks for playin.
