Question

a stream of water will bend toward a balloon that has been rubbed on a sweater to generate static charge. which property of water is responsible for this behavior?

A. The polarity of the water molecule
B. The ability of water to for hydrogen bonds with itself
C. The heat capacity of the water molecule
D. The ability of water molecules to form a repeating lattice structure

Answer 1

A. the polarity of the water molecule because the balloon is negatively charged and the positive hydrogen end of the water molecules are attracted to it

Answer 2

Answer is A. The polarity of the water molecule

Water is a polar molecule due to an uneven distribution of electron density. Water has a partial negative charge near the oxygen atom and partial positive charge near the hydrogen atoms. Thus, dipole moment is created when there is a charge separation between the molecules. The dipole moment of water is 1.85. Therefore, when the charged balloon is placed close to the stream of water, it cause all the molecules of water to bend towards the balloon which has static charge on it.
