walters Posted June 14, 2005 Report Share Posted June 14, 2005 To stack Liquids on top of each other what is this called in chemistry? I put a liquid in a cup jar and to stack another liquid form on top of it i have to use a spoon to slow down the liquid to make it stack on top of the first liquid in the cup. What is this called in chemistry? Why does the spoon slow down the liquid? What does the spoon do really? does it displace the liquid? Why does it slow it down? I seen a Chemistry Funnel with a value what is the name of this chemisty funnel they use for chemistry to mix or break up the density?

walters Posted June 15, 2005 Author Report Share Posted June 15, 2005 which should mean that the two liquids won't mix at all. The 2 liquids are stacked on top of each other the spoon slows down the liquid because it absorbs the impact of the liquid as it falls down and hence prevents the liquid from possibly sinking down suddenly due to the impact of the fall, due to the surface tension of the liquid at the bottom Spoon=absorbs the liquid How does the spoon slow the liquid down? What is the spoons function in these process? What is the spoon acting as? Quote Link to comment Share on other sites More sharing options...

Factors include density, temperature (as it changes the density), surface tension, and the presence of air. However, the main one is that the two liquids are not being mixed, but only carefully placed on top of each other, using the spoon to prevent mixing from starting.

walters Posted June 15, 2005 Author Report Share Posted June 15, 2005 How does the spoon do this effect ? why does the spoon do this? and how? It "Builds" layers how does the spoon do this? Quote Link to comment Share on other sites More sharing options...

It doesn't build the layers. That's like saying the pyramids made the north star. The spoon has to be in the right place at the right time. It acts as a physical barrier and diffusion device to deliver the payload to the target with the minimal impact. If the spoon were under the surface, it would not work. If the spoon were too high, it would not work. If the spoon were on edge, it would not work. It works by slowing the liquid(s), and preventing turbulance and mixing. Density differences maintain it. I happen to know the cream should be cold, as should the spoon, and the coffee at the boil, to increase the odds of success. Quote Link to comment Share on other sites More sharing options...
walters Posted June 16, 2005 Author Report Share Posted June 16, 2005 Thanks for the help spoon= diffusion device and give minimal impact. So the spoon is a Diffusion device? Is the spoon controlling the turbulance? the flow of the turbulance? Quote Link to comment Share on other sites More sharing options...
