Why does water move from the roots to the leaves of plants?
Solutes push the water up the plant.
Capillary action pulls the water molecules like a chain against gravity.
Water is pulled by gravity through the plant body.
The high specific heat of water allows water to move freely through the plant.
Water is polar because.....
The unequal sharing of electrons gives the water molecule a slight negative charge near its oxygen atom and a slight positive charge near its hydrogen atoms.
The molecule has two poles, which one results in the poles being colder than other regions of the molecule.
The unequal sharing of electrons gives the water molecule a slight negative charge near its hydrogen atoms and a slight positive charge near its oxygen atom.
The water molecule is neutral and therefore the two poles cancel each other out.
Select all that apply: A polar molecule has these characteristics.

When water molecules stick to other surfaces
The property of water that allows water to move up a thin tube (or the stem of a plant) by itself
What is the relationship between the diameter of a tube and height of a capillary water column?
The smaller the diameter of a tube, the smaller the height of the water column
The smaller the diameter of a tube, the larger the height of the water column
The diameter of a tube does not relate directly to the heigh of the water column inside it
Water displays many important properties such as...

-Having a high heat capacity/heat of vaporization
-Being a universal solvent
These properties arise due to which of the following:
Water is a nonpolar substance
Hydrogen and oxygen bond ionically which leads to these properties

Hydrogen bonds are an example of an...
Intramolecular force
Intermolecular force
The polar covalent bond between oxygen and hydrogen is an example of an....
Intramolecular force
Intermolecular force
The polar covalent bond between hydrogen and oxygen occurs because...
Oxygen and hydrogen are nonmetal atoms
Oxygen is more electronegative and pulls electrons closer to itself
Electrons are transferred from the hydrogen atoms to the oxygen atom
Oxygen and hydrogen are metal atoms
An insect like a water strider can skate along the top of a pond because:
covalent bonds result in water cohesion
hydrogen bonds result in water cohesion
ionic bonds result in water cohesion
