has to do with alkaline dip tanks.. Water break free surface is a 10 second retention of water on a surface that has been cleaned and rinsed of its alkaline.

Why free surface effect is detrimental in ro-ro ferries?
RO-RO ferries have large open decks (car decks) without any sub division or bulkheads. Hence a small amount of water would be able to impart a significant free surface effect.
Can you glue cpvc without primer?
You should scratch the surface or use a piece of sand paper on it to break the surface coating.
How do you move a block of wood without touching it?
Is the block of wood floating in water? If so, then a drop of dishwashing soap dropped into the water next to the wood, will cause the wood to float away from the drop of soap. The effect is quite pronounced on small pieces of wood, and it is positively dramatic on tiny things like parsley flakes floating on the water. What's happening is that the piece of wood floating in the water is acted on by the surface tension of the water. The water pulls in every direction, so the wood doesn't move. A tiny drop of soap will break the surface tension of the water, and the surface tension on all the OTHER areas of water will cause the wood to be pulled away from the soap drop.
What protects the surface of a plant from water loss?
epidermis
How does water pressure break pipes?
If a forced hot water connection breaks, is this a covered item?
What are three reasons why you have tides?
# Free surface water # Masses in separate locations # The body with free surface water is rotating.
How do you describe volcanic islands when they first break the water's surface?
Atol
How does an ant not sink in water?
It has neither the shape nor the weight to break the surface tension of the water.
Why a clip float in water?
Because the paperclip is not dense enough to break the surface tension of the water
What are the 4 forces that cause rocks on earths surface to break down?
Water erosion
When you pour too hot or too cool water or ice in a beaker why the beaker will break?
Due to surface tension the beaker will break.
Cuticle in plants helps in preventing?
Evaporation of water from free surface
Why would a pin float if you just dropped it in water?
Because of surface tension on the top of the water. Surface tension is when the water molecules stick together allowing a small, light object to "float" on the surface. If you genitally pushed on the pin after is settled on the water, you would break the surface tension and the pin would sink.
Is soap the only substance that can break the waters surface tension?
detergents and water striders can also do that.
What happen to the water as it receive energy a heat coming from the sun?
Water molecules move faster due to more kinetic energy, and possible evaporation will occur as some water molecules at the surface break the Hydrogen intermolecular bonds, escape, and become free-floating gases.
How would you use the particle theory to explain what happens when radiant energy form the sun heats a pond?
RRadiant energy from the sun strikes the water particles at the surface of the pond. The water particles gain energy and break free of the water. Thus, the liquid water particles escape to form water vapor.
What is the process called when fast moving molecules break away from the surface of liquid water to from water vapor?
evaporation i think but i am not sure
