Questions and Answers

1.

The change of state between Liquid and Gas (Not just water and steam) is generally called what?
- A.
  
  Boiling
- B.
  
  Ionization
- C.
  
  Vaporization
- D.
  
  Evaporation
- E.
  
  Sublimation
Correct Answer
C. Vaporization

Explanation
Vaporization is the correct answer because it refers to the process of converting a liquid into a gas. This change of state can occur for various substances, not just water and steam. During vaporization, the molecules of the liquid gain enough energy to overcome the intermolecular forces holding them together, allowing them to escape into the gas phase. Therefore, vaporization is the most appropriate term to describe the change of state from liquid to gas.

Which of these reacts more strongly?
- A.
  
  Lithium
- B.
  
  Francium
- C.
  
  Potassium
- D.
  
  Caesium
- E.
  
  Rubidium
Correct Answer
B. Francium

Explanation
Francium reacts more strongly compared to the other elements listed. This is because francium is the most reactive alkali metal due to its large atomic size and low ionization energy. It readily loses its outermost electron, resulting in a strong reaction with other elements or compounds.

Carbon is a _____ at room temperature (state of matter)

Correct Answer
Solid

Explanation
Carbon is a solid at room temperature because it exists in the form of graphite or diamond, both of which have a highly organized and rigid molecular structure. In the solid state, the carbon atoms are closely packed together, resulting in a stable and fixed arrangement. This allows carbon to maintain its shape and volume, characteristic of a solid, rather than flowing or taking the shape of its container like a liquid or gas would.

4.

Which of these is Sea waters value on the pH scale and is Alkaline or Acid?
- A.
  
  8 Acid
- B.
  
  5.6 Alkaline
- C.
  
  8 Alkaline
- D.
  
  13.2 Alkaline
- E.
  
  13.2 Acid
Correct Answer
C. 8 Alkaline

Explanation
Sea water has a pH value of 8, which indicates that it is alkaline. The pH scale ranges from 0 to 14, with values below 7 being acidic, 7 being neutral, and values above 7 being alkaline. Therefore, a pH value of 8 classifies sea water as alkaline.

5.

Rain water is naturally acidic. What acid is it?
- A.
  
  Hydrochloric
- B.
  
  Gastric
- C.
  
  Ethanoic
- D.
  
  Carbonic
- E.
  
  Sulphuric
Correct Answer
D. Carbonic

Explanation
Rain water is naturally acidic due to the presence of carbonic acid. This acid is formed when carbon dioxide in the atmosphere dissolves in rainwater, creating a weak acid. Carbonic acid is responsible for the slightly acidic nature of rainwater, which can have a pH value below 7.

Hydrogen Oxide is more commonly refered to as what?
- A.
  
  Hydrogen Gas
- B.
  
  Ozone
- C.
  
  Water
- D.
  
  Rust
- E.
  
  Diesel
Correct Answer
C. Water

Explanation
Hydrogen Oxide is commonly referred to as water. Water is a chemical compound composed of two hydrogen atoms bonded to one oxygen atom. It is a colorless, odorless, and tasteless liquid that is essential for all known forms of life. Water is widely used for various purposes, including drinking, cooking, cleaning, and industrial processes. It is also found in abundance on Earth's surface, covering about 71% of the planet.

The scientific formula E=MC²means what?
- A.
  
  That the energy of an object is equal to its mass time the speed of light squared.
- B.
  
  That the emulsive properties of an object are equal to its amount of magnesium atoms times the amount of its carbon atoms squared.
- C.
  
  That the energy of an object is equal to its momentum times its curvature squared.
- D.
  
  That the ethical sensitivity of a wire is equal to its resistance times its length squared.
- E.
  
  That the kinetic energy of an object is equal to its mass times its velocity squared.
Correct Answer
A. That the energy of an object is equal to its mass time the speed of light squared.

Explanation
The formula E=MC2 represents the relationship between energy (E), mass (M), and the speed of light (C). It states that the energy of an object is equal to its mass multiplied by the speed of light squared. This equation, derived from Einstein's theory of relativity, demonstrates the equivalence of mass and energy and highlights the immense amount of energy that can be generated from a small amount of mass.

Chlorine reacts with what on your body?
- A.
  
  Anything that is dark
- B.
  
  Everything
- C.
  
  Anything that is dry
- D.
  
  Anything that is wet
- E.
  
  Every living cell
Correct Answer
D. Anything that is wet

Explanation
Chlorine reacts with anything that is wet on your body because chlorine is a highly reactive chemical that readily combines with water molecules. When chlorine comes into contact with wet substances, such as sweat or water on the skin, it can cause a chemical reaction that may result in skin irritation or other adverse effects.

The law of the conservation of energy states that energy can neither be ________or _______ ?

Correct Answer
created or destroyed, destroyed or created

Explanation
The law of the conservation of energy states that energy cannot be created or destroyed. This means that the total amount of energy in a closed system remains constant over time. It can only be transferred or transformed from one form to another. Therefore, the correct answer is "created or destroyed, destroyed or created".
