Why is it that a needle may float on a clean water but sink when detergent is added to the water?
Because the detergent reduces the surface tension of the water.
Does the needle float or sink in water?
A needle sink in water.
How does a needle float on water?
the way it float is surface tension!!
Why does one liquid float on one another?
The liquid which is less dense will float on top of the liquid which is more dense. Density affects the liquid's level.
When will an object float in a liquid?
An object will float in a liquid when the density of the liquid is higher than that of the object or when equal. That is to say Upthrust= or >weight of the object
How can a sewing needle float on the surface of water?
The needle does not break the surface tension (meniscus). Get a small piece of toilet tissue and lay it on a glass of water. lay a needle on the tissue. The tissue will become sodden and sink, leaving the needle floating on the surface tension. Put the smallest drop of washing-up liquid on the water. The surface tension will be destroyed and the needle will sink. Try it.
What liquids can a needle float on?
A needle can be made to float on very still water.
Why is it that a needle may float on a clean water but sink when detergent is added to the water?
Because the detergent reduces the surface tension of the water.
Can you float a needle?
Yes, you can float a needle I have done it before. It doesn't have to do with density though it has to do with surface tension.
Does the needle float or sink in water?
A needle sink in water.

What do cell organelles float around inside a cell?
This is called the cytoplasm which fills the cell.
Can a needle float in soapy water?
Yes it is not possible. Because as soap is added then surface tension would get reduced and so possibility of float becomes less. When we carefully place the same needle on ordinary water floating is quite possible as water has more surface tension
What has to have more density for an object to float on water the object or water?
Normally the water - to float and object has to displace a volume of water equal to its mass. If its density is greater than that of water, the maximum mass of water it can displace is its own volume which, as the water is less dense that it, will have less mass than the object and it will sink. However, for small light objects the surface tension of water comes into play - it is possible to float a steel sewing needle (with a density greater than water) on water by gently dropping a clean needle on its side onto the water surface so that it does not break the surface tension. With a needle floating, adding a few drops of washing up liquid to the surface reduces the surface tension and the needle will then sink.
Why gas come from carburetor after you shut down?
The problem is most likely in the float bowl. The float could be bad. The likely cause is the needle valve that is control by the float is stuck, or dirt has gotten between the needle and needle seat. This is an easy fix. Carefully remove the float bowl. The float will be held in place by a pin. Remove the pin, and float. Check that there is no fuel in the float, and that it floats in gas, if not replace. The needle valve will come out with the float, as they are connected by a wire link. Make sure needle vale is clean, and able to move freely inside it's housing. Check the bottom of the housing at the needle seat to make sure it is clean of dirt. Reassemble, and you should be ready to go.
Will a boat float on liquid soap?
Yes the boat will float on liquid soap
Why does 302 2 barrel engine diesel?
I would suspect a bad needle valve and seat in the carburetor. The float level can also be set too high. I would replace the needle valve and seat and check float level.I would suspect a bad needle valve and seat in the carburetor. The float level can also be set too high.
