i need help please befor i get grounded on my birthday week
Water allows materials to rest upon it if the surface tension is not broken. Pollen, dust, water insects, and other biological materials are able to remain on the surface of the water because of this tension

3.Water ordinarily freezes at 0 degrees Celsius or 32 degrees Fahrenheit. In a system at this temperature, the rate of freezing is the same as the rate of melting. This is known in chemistry as a dynamic equilibrium. Any change in the temperature will change the rates of freezing and melting, and the entire system will freeze or thaw. Adding salt changes these rates but without changing the temperature. The salt causes the rate of freezing to occur slower than the rate of the rate of thawing, causing the ice to melt and requiring a lower temperature to reattain equilibrium....lol i need some1 to type for me...
4.The diverse properties related to how water molecules hold onto other molecules, other substances in the water, the temperature and the property of things interacting with the water. The strength of molecules holding onto each other provides the basic property for surface tension.
hmm....above one marked 4, belongs to the 5th question.
4.Higher temp causes H bonds to break
Lower causes them to stabilize
Adhesive and cohesive properties are based on h bond....my brain and typing skills increased...lol..
i want to thank so so much for your help dont get to realxed.... ILL BE BACK!!
