Quiz Questions Over The Properties Of Water - Quiz

This quiz checks students basic knowledge of the properties of water.

Questions and Answers

1.

Which atom/s of the water molecule has a slightly positive charge?
- A.
  
  Oxygen
- B.
  
  Helium
- C.
  
  Hydrogen
- D.
  
  Lithium
- E.
  
  Ozone
Correct Answer
C. 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?
- A.
  
  Oxygen
- B.
  
  Helium
- C.
  
  Hydrogen
- D.
  
  Lithium
- E.
  
  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.

A molecule that has electrically charged areas is called a ____________________ ?
- A.
  
  Solution
- B.
  
  Solvent
- C.
  
  Specific Heat
- D.
  
  Polar Molecule
- E.
  
  Charged Particle
Correct Answer
D. 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.

The opposite poles of water molecules are attracted to each other and causes water molecules to "stick" together. This force is _________________ ?
- A.
  
  Potential
- B.
  
  Radiation
- C.
  
  Nuclear
- D.
  
  Magnetic
- E.
  
  Electrical
Correct Answer
E. 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.

Which property of water that causes it to rise in a tube?
- A.
  
  Surface tension
- B.
  
  High specific heat
- C.
  
  Universal solvent
- D.
  
  Capillary action
- E.
  
  Changing state
Correct Answer
D. 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.

Which property of water allows the insect called a water stryder to skate across the surface of a pond?
- A.
  
  Surface tension
- B.
  
  High specific heat
- C.
  
  Universal solvent
- D.
  
  Capillary action
- E.
  
  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.

When one substance dissolves in another it is a ________________ ?
- A.
  
  Solvent
- B.
  
  Capillary action
- C.
  
  Specific heat
- D.
  
  Solution
- E.
  
  Surface tension
Correct Answer
D. 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 process in which liquid water becomes a gas is called evaporation.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
Evaporation is the process by which liquid water changes into a gaseous state. During evaporation, heat energy is supplied to the water, causing the water molecules to gain enough energy to break free from the liquid and become water vapor. This process occurs at the surface of the liquid and is influenced by factors such as temperature, humidity, and air movement. Therefore, the statement that the process in which liquid water becomes a gas is called evaporation is true.
