How do soapy water drops stay on a penny?
When soapy water is dropped on a penny, the surface tension of the water allows it to form a dome-like shape rather than immediately spreading out. The soap molecules reduce the surface tension of the water, allowing it to adhere to the penny and form a cohesive drop.
Does plain water evaporate faster than soapy water?
Plain water typically evaporates faster than soapy water because soap reduces the surface tension of water, making it less likely to evaporate quickly. This is due to the soap molecules forming a layer on top of the water that can inhibit evaporation.
What have a slippery soapy feel acid base or neutral solution?
A base has a slippery soapy feel.
How many drops of soapy water fit in a penny?
Ideally, everyone performing the experiment would include the following: - distilled waterThere are a lot of factors involved. The cohesion and adhesion ('stickiness') of water molecules can be effected by things like oils (on surface pennies from peoples' skin) and other contaminates on the penny. The size of the dropper or pipette will determine the size of each water droplet - the larger the drop, the fewer number of drops will fit on the penny. The manner in which the water is added to the penny is also a factor. Water has a cohesive nature (the molecules are kind of like magnets and are attracted to one another). Therefore, if the drop from the pipette is allowed to touch the water already on the surface of the penny, the water can be 'pulled' out of the dropper. When this happens, the size (volume) of the drop is not always the same - it could be a very small amount (which will result in a very large number of drops), or a large amount. Soap causes the cohesiveness ('stickiness') of the water molecules to decrease so they are not as strongly attracted to each other. Because of this, when soap is added to the water the number of drops that can be placed on the penny will decrease. The water molecules can't 'stick' together as well, so the water on top of the penny spills off sooner than it would with non-soapy water. Ideally, everyone performing the experiment would include the following: - distilled water (to start with) - same type/size of calibrated dropper/pipette - same date of penny - penny cleaned as thoroughly as possible using same cleaning procedure - same 'dropping' procedure
What is the lustre of magnesium?
that is how u remove a fingerprtint.... jk just saying maybe water maybe furniture polish maybe vinegar maybe windex maybe white bread maybe alchohol maybe soapy water or maybe to make it easy just be rational, you dont have to be genuis, just wear some gloves
Can soapy water melt?
Soapy water itself does not melt as it is already in a liquid state. However, the soap molecules within the water can break down when exposed to heat, which can affect the properties of the soapy water.
Does sugar dissolve quicker in salt water or soapy water?
Sugar would dissolve faster in soapy water. Sugar dissolving is actually the sugar molecules bonding with the water molecules. In salt water, sodium has already bonded with the water molecules, leaving no room for more bonding with sugar molecules. Soap, on the other hand, is a very mild base. It isn't so much a bonded element with water as it is a mixture. All of the water molecules are still available for bonding with sugar.
Soapy water specially when frothy?
Soapy water appears frothy because of the presence of air bubbles trapped within the soap molecules. When the water is agitated or shaken, it creates more foam by incorporating more air, giving it a frothy appearance.
Why does soapy water do not have surface tension?
Soapy water does have some surface tension to it but it is very negligible. However pure water have good surface tension due to strong hydrogen bonding. This is the reason a water strider bug can walk and paperclip will float on water.
What substance either contains hydroxide ions or reacts with water to from hydroxide ions?
A substance that contains hydroxide ions is sodium hydroxide (NaOH). In contrast, some substances that react with water to form hydroxide ions include magnesium hydroxide (Mg(OH)2) and calcium hydroxide (Ca(OH)2).
What is a soapy water especially when frothy?
Soapy water that is frothy typically indicates that the water has been agitated or mixed with soap, causing the formation of bubbles. The soap molecules help to reduce surface tension and trap air, creating a foam or froth on the surface of the water.
What did soapy do to get arrested in the cop and the anthem?
soapy was not allowed
How do you say soapy in french?
Soapy (containing soap, as in soapy water) is 'savonneux' (masc.) or 'savonneuse' (fem.) in French.
How can you use the word soapy in a sentence?
After washing the dishes, there was a soapy residue left in the sink.
How do you put soapy in a sentence?
Please soak this in soapy water.
How does a bubble evolve?
Bubbles are made up of water molecules that sticks together. Basically, to make a bubble you need a soapy water to easily form a hollow sphere.
How do soapy water drops stay on a penny?
When soapy water is dropped on a penny, the surface tension of the water allows it to form a dome-like shape rather than immediately spreading out. The soap molecules reduce the surface tension of the water, allowing it to adhere to the penny and form a cohesive drop.
