Does water stay warmer for longer if it has soap in?
Yes, if pure water and soapy water are present at the same temperature (say 70 Celsius) then soapy water takes long time to return to the normal temperature because its Enthalpy (Energy content) is higher than normal water.
Why is the pH of soap 9?
The Ph scale is from 0-14. 7 is neutral. So, 9 would be increasing to alkaline. below 7 is acidic. Red litmus paper would turn blue in soapy water, and blue litmus paper would stay blue. Soapy water is a base.
Why does it stay suspended at the edge of the leaf?
Dew drops
Why can cold water in an uncapped vacuum flask still stay cold?
It will certainly not stay cold as long as if it were capped.
Can water help fire stay lit?
no, fire does not work well with water and the water can only be used to exstinguish the fire.
What property of water allowes so many drops of water to stay on a penny?
adhesion
Why can you fit more fresh water drops on a nickel then soapy water drops?
Because the hydrogen molecules in water want to stay connected and once you add soap it messes with the bonds and and they don't stay bonded as strongly. Also the mass and density of the water changes when you add soap.
Does water stay on coin or spread out?
Depends soapy water makes the bond between the water particles weaker. So if you add soapy water then it won't last as long
Why does water stay long on a penny?
it will change the color to brown
Why does water stay on a penny?
Surface tension allows water to form a large drop on a penny before popping and spilling off.
Does water stay warmer for longer if it has soap in?

What makes the soap feel soapy?
There is no chemical reaction. Lathering is just air bubbles getting trapped inside the liquid. Soap has a high surface tension, and so if you introduce air bubbles inside it, they tend to stay for a while (unlike water for instance, where the air bubble won't stay for long and will just rise to the surface and fall out). This is also why you can blow soap bubbles (but not water bubbles).
Drops of water or ice crystals become too large to stay suspended in cloud?
condesation
When water vapour condenseit form tiny drops of water that forms clouds when do this droplets come down as rain?
Individual droplets are so small, that they can stay suspended in the air. If the droplets combine into larger drops that are too heavy to stay suspended, they fall as raindrops.

What can you use to write on frosted glass?
to get it to stay, soapy stuff! or oily stuff
Why does a water drop form a sphere?
Water (H2O) is very cohesive, meaning that its molecules tend to stick to each other. Cohesion of water is especially strong due to an H2O's ability to make up to 4 hydrogen bonds with other water molecules. This principle is also responsible for the common elementary experiment in which many drops of water are dropped on a penny head, yet the water manages to stay on top. Its cohesiveness is due to
