Quiz Questions Over The Properties Of Water

2.

Which property of water allows the insect called a water stryder to skate across the surface of a pond?

Surface tension
High specific heat
Universal solvent
Capillary action
Changing state

Correct Answer

A. Surface tension

Explanation

Surface tension is the property of water that allows the insect called a water strider to skate across the surface of a pond. Surface tension is the result of the cohesive forces between water molecules, causing them to form a "skin" or "film" on the surface. This strong surface tension allows the water strider to distribute its weight and effectively walk on water without sinking.

The temperature in Celsius in which water boils?

212
100
32
0
50

Correct Answer

A. 100

Explanation

Water boils at 100 degrees Celsius. This is the boiling point of water in the Celsius temperature scale.

Which atom/s of the water molecule has a slightly positive charge?

Oxygen
Helium
Hydrogen
Lithium
Ozone

Correct Answer

A. Hydrogen

Explanation

In a water molecule, oxygen attracts the shared electrons more strongly than hydrogen due to its higher electronegativity. This causes the oxygen atom to have a slightly negative charge, while the hydrogen atoms have a slightly positive charge. Therefore, the correct answer is hydrogen.

Which atom/s of a water molecule has a slightly negative charge?

Oxygen
Helium
Hydrogen
Lithium
Ozone

Correct Answer

A. Oxygen

Explanation

The oxygen atom in a water molecule has a slightly negative charge. This is because oxygen is more electronegative than hydrogen, meaning it has a greater ability to attract electrons. As a result, the shared electrons in the covalent bonds between oxygen and hydrogen are pulled closer to the oxygen atom, giving it a partial negative charge. The hydrogen atoms, on the other hand, have a partial positive charge. This polarity of the water molecule allows it to form hydrogen bonds and gives water its unique properties.

The temperature in Celsius in which water freezes?

212
100
32
0
50

Correct Answer

A. 0

Explanation

Water freezes at 0 degrees Celsius. This is the temperature at which water transitions from a liquid state to a solid state.

Which property of water that causes it to rise in a tube?

Surface tension
High specific heat
Universal solvent
Capillary action
Changing state

Correct Answer

A. Capillary action

Explanation

Capillary action is the property of water that causes it to rise in a tube. This phenomenon occurs due to the cohesive forces between water molecules and the adhesive forces between water molecules and the walls of the tube. These forces allow water to climb against gravity in narrow spaces, such as the tiny tubes in plants or the spaces between fibers in a paper towel. This is why water can be drawn up through a narrow tube, like in a capillary tube or a straw.

A molecule that has electrically charged areas is called a ____________________ ?

Solution
Solvent
Specific Heat
Polar Molecule
Charged Particle

Correct Answer

A. Polar Molecule

Explanation

A molecule that has electrically charged areas is called a polar molecule. This is because polar molecules have a slight positive charge on one end and a slight negative charge on the other end, creating an electrical polarity. This polarity is due to the unequal distribution of electrons within the molecule, causing one end to be more electron-dense and the other end to be less electron-dense. This charge separation gives rise to various properties and behaviors of polar molecules, such as their ability to dissolve in other polar substances and their interactions with electric fields.

When one substance dissolves in another it is a ________________ ?

Solvent
Capillary action
Specific heat
Solution
Surface tension

Correct Answer

A. Solution

Explanation

When one substance dissolves in another, it forms a solution. A solution is a homogeneous mixture where the solute (substance being dissolved) is evenly dispersed in the solvent (substance doing the dissolving). This process occurs at the molecular level, where the solute particles separate and disperse throughout the solvent particles, resulting in a uniform mixture.

The opposite poles of water molecules are attracted to each other and causes water molecules to "stick" together. This force is _________________ ?

Potential
Radiation
Nuclear
Magnetic
Electrical

Correct Answer

A. Electrical

Explanation

The force that causes water molecules to "stick" together is electrical. The opposite poles of water molecules, which are the positive and negative charges, attract each other and create this electrical force. This force is responsible for the cohesion and surface tension of water.
