1.3B: Transferring Methods - Liquids - Chemistry LibreTexts
WEBIf pouring from an Erlenmeyer flask, or transferring a liquid into a vessel containing a narrow mouth (e.g. a round bottomed flask), a funnel should be used. Funnels can be securely held with a ring clamp (Figure 1.17b), or held with one …
Water Pouring: Why Does Water Stick To Glass When Pouring?
WEBOct 19, 2023 — When the angle between vertical direction and the glass wall is small, surface tension is stronger and the component of gravity perpendicular to the glass wall is small; consequently, water sticks to the outside surface of the container (or in other words, runs down the side of the container).
How do I pour from a mug without having it drip so much?
WEBIf you're pouring, say, from a mug into a pot, just dump it out, and hope it doesn't all splash out. If you can't reasonably dump it out, tilt the cup as much as you can, so that the liquid will move faster.
Go with the Flow - Scientific American
WEBSep 6, 2018 — Do some show turbulent flow when water is poured quickly? Some water bottles have a small hole near the spout in the lid—why would this be? Why does liquid not flow out from this small hole?
Fantastic feats: experimenting with water – Science in School
WEBMar 31, 2021 — Water was poured in through the cloth, so why doesn’t it pour out again? To pour the water out turn the cup upright again quickly, then tip up the cup slowly while pressing a finger on the nylon (figure 2, right).
Why does water pouring from a glass sometimes travel down the …
WEBComponent of gravity perpendicular to glass pulls water away from glass wall, and surface tension pulls water to glass wall. When the angle between glass wall and vertical direction is small, component of gravity perpendicular to glass wall is small and surface tension prevails.
Decanting, gravity filtration and liquid transferring - Safrole
WEBIt is best to pour as if attempting to decant, meaning to keep the solid settled in the flask for as long as possible. When solid begins to pour onto the filter paper, it has the possibility of clogging the filter paper pores or slowing filtration.
Measuring the Volume of Liquids - Harper College
WEBWhen liquid is poured from a piece of glassware a small amount remains behind, clinging to the sides of the vessel. A 100 ml volumetric flask is designed to hold exactly 100 ml, but if the liquid is poured out it will actually deliver a little less than 100 ml. Glassware designed to deliver, like pipets and burets, are marked with a TD .
Chemistry Glassware Types, Names and Uses - ThoughtCo
WEBMay 18, 2024 — Specialized glassware such as Florence flasks and volumetric flasks are used for heating and preparing solutions with high accuracy. Common types of lab glassware include beakers, flasks, and test tubes, all …
Physics of the inverted bottle dispenser
WEBThe reason why pouring the bottle is intriguing is that it empties itself in bursts. A bubble of air gets in, and water gets out at once. But if you do it in a controlled way, you will end up in the initial configuration I described, and from that point onwards, no air can get in.
