What must happen to water in the liquid phases for it to become water in the gaseous phase?
The hydrogen bonds between Hydrogens of one water molecule and the oxygen of another water molecule must break. These are not actual bonds but they are interactions of the dipole moments produced by the difference in electronegativity between the hydrogen and oxygen atoms in a single water molecule. When enough heat or drop in pressure is produced the molecules will dissociate from one another and enter a vapor phase.
When a drop of phenolphthalein is introduced in lime water the solution turns?
When a drop of phenolphthalein is introduced in lime water the solution turns pink in colour.

Why pour acid into water while stirring but never add water to acid?
Because when you drop water into acid the acid is too concentrated so it has to let out a reaction to drop the concentration.

Why do water droplets always form one huge drop on a penny?
Surface tension of water draws it into a larger drop. It will do that on any nonporous surface- metal, glass, smooth plastic, etc.
What is released when calcium levels drop?
carbon dioxide
How are stalactite and stalagmite formed?
Slightly acid water seeping through the joints in the limestone overlying the cave dissolves calcium carbonate form from the rock, then precipitates it as the crystalline mineral, calcite, on emerging through the cave roof. Each drop of "hard" water may leave only a few molecules of calcite, but drop after drop after drop... the deposits develop.

What causes stalactites to form?
This is caused by the concentration of minerals solidifying over time, normally from groundwater trickling through cracks in the roofs of such caverns contains dissolved calcium bicarbonate. When a drop of water comes in contact with the air of the cavern, some of the calcium bicarbonate is transformed into calcium carbonate, which is precipitated out of the water solution and forms a ring of calcite on the roof of the cavern.
How is lime water prepared?
1 lime 1 tsp sugar Water Ice cubes Measure the sugar, and dissolve in 1tsp boiling water. Pour into a glass. Add the lime, and fill up the rest of the glass with water, and drop in the ice cubes, but they are not really needed.
How much calcium in one drop of sperm?
Aproximately 67 units
Dose every water drop follow the same path?
It can and it sometimes it can't. It depends if the water drop was close to it. If was close to it the water drop would attrack the next water drop you drop
Imagine you are heating a pot of water You drop a small metal pellet into the water and notice the pellet moves up and down through the water in a circular pattern Which process is causing the pel?
Convection is causing this.
Is a drop of blood same size af a drop of water?
No it is not, a drop of blood is smaller than a drop of water but if you drop two drops of blood then that equals the right amount of water :)
