What makes water have surface tension?
Surface tension is The attraction of molecules to each other on a liquid's surface? Surface tension of water is the physical property of hydrogen bonding that makes the water molecule. The way that this works is that a water molecule (H2O) is a polar molecule. This is because the oxygen has a much higher electronegative value than the hydrogen. This means that the oxygen gets a lot higher 'share' of the shared electrons than the hydrogen does. This gives oxygen a very high partialnegative charge, and the hydrogen a very high partial positive charge. Because of these high partial charges on each end of the molecule, they are very highly attracted to each other
What is the shape of graph of Stoke's Law of different ball bearings through glycerol and how to find viscosity of glycerol from graph?
The graph will be a straight graph if you plot r2 against v. If we calculate the gradient of the line this is giving us the value of the constant "k" from the equation: k = v r2 With this calculated value of "k" we can calculate the value of the viscosity of the liquid using: Viscosity = 2(Denisity of sphere - Denisty of Glycerol) g 9k
What is the accepted value for the heat of solution NH4Cl?
The accepted value for the heat of solution of NaOH is -44.2 kJ/mol
What concentration indicates a basic solution?
I think you mean the pH value, it so, a basic solution has any value exceeding 7.
What happen with you mix pH solution with soap?
This depends on the pH value of this solution !
The unit of surface tension is?
Surface tension is basically a force acting on the surface of a fluid.so the units will be newtons(N) and dimensions are MLT-2But generally we talk in terms of surface tension coefficients which is surface tension per unit length.Vishesh MadanSurface tension is perpendicular force acting per uint length of an imaginary line stretched on the surface of a liquid. Therefore, SI units will be N/m, since the value of surface tension for all liquids is very low therefore it is commonly mentioned as mN/m. Dimensions formula for surface tension will be MT-2.In another case Surface tension is also measured as work done to streach a unit surface area of a film, in that case units will be J/m2.K Singh

Does fresh water have more surface tension than salt water?
Cold water has stronger (better) surface tension.Surface tension is dependent on temperature. For that reason, when a value is given for the surface tension of an interface, temperature must be explicitly stated. The general trend is that surface tension decreases with the increase of temperature, reaching a value of 0 at the critical temperature.From: http://en.wikipedia.org/wiki/Surface_tensionAdded emphasis for readability.dfsfdytrhjtkjkjh
Which characteristic of water molecules directly contributes to the remarkable water walking success of insects?
This is the surface tension. The value for water is great - 58,85 dyn/cm.
Can a tension have a negative value?
yes
If the PH value of solution is 13 what is the solution?
A basic solution.
How do you know if a value a is a solution to an equation?
If this value a satisfy the equation, then a is a solution for that equation. ( or we can say that for the value a the equation is true)
How is this different from determining if a value is a solution to an equation?
How is this different from determining if a value is a solution to an equation?
What is the relation between pH value and nature of the solution?
The nature of the solution be it acidic or basic will determine the PH value of the given solution.
What is a value for the variable that makes the statement true?
Such a value is called a "solution" or "root" of an equation.
At what altitude above the earth surface the value of 'g' reduces to half of its value at the surface?
at about 9km above the surface of the sea.
What Is the pH value of hydrochlorlic acid?
The pH value of an acid solution depends on its concentration and the temperature of the solution.
