Is styrofoam the same as polystyrene?
They are made from the same polymer, polystyrene. Usually polystyrene is clear, hard and rigid, for example in CD cases. However, styrofoam is created by blowing air through liquid polystyrene. The bubbles are locked in the polystyrene as it solidifies, giving the syrofoam used in packaging and cups. The reason it is compressible is because the air is compressed, rather than the hard, rigid polystyrene itself.
How does water dissolve chalk?
Rather badly.
Why do you use conical flask in the titration process rather than beaker?
It prevent the solution from spelling
Do solids dissolve better in hot or cold water?
Dissolving is caused by the small rapid movements of the atoms or molecules. The faster they are moving, the better substances dissolve. As the molecules have more energy and therefore move faster in hot water, substances dissolve better there.
Why must the stem of the funnel touch the inside surface of the collecting beaker during filtration?
it's done to minimize the mixing of air into the filtered solution. By touching the stem to the collecting beaker, the solution flows into the beaker smoothly rather than splashing into it.
How do you describe the beaker?
The beaker is a glass container with an approxiamate capacity of 300ml. It is fragile and can break rather easily. There are markings on the beaker to allow the estimation of liquid volumes.

How of increasing the amount of a substance that will dissolve in a liquid?
I can dissolve more sugar in hot tea rather than cold tea.

What is the difference between glass and beaker?
well there really is know difference its just a beaker is a thiker kind of glass rather than ordinary glass!! ps if that helped please reply back:-)
Why does hard candy dissolve faster in sprite rather than water?
skittles
Why oil and water dissolve?
the density of oil is more than the water.so,they will never dissolve with each other, rather the oil will float over the water.
Why the sugar and chocolate dissolve faster in hot water?
The sugar actually melts, rather than disolving.
