What is the main difference between an element and a compound?

Elements are made of one type of atom, while compounds are made of two or more different atoms chemically bonded.

Compounds are made of one type of atom, while elements can contain different atoms.

Elements are pure substances, while compounds are mixtures.

Elements can be broken down into simpler substances, while compounds cannot.

What is the main characteristic that distinguishes a compound from a mixture?

Mixtures can be separated by physical means, compounds cannot.

Compounds are always liquids, mixtures are not.

Compound have variable compositions, mixtures do not.

Mixtures are chemically bonded, compounds are not.

What is the main purpose of the periodic table?

To organize elements by atomic number.

To provide a history of chemistry.

To list elements alphabetically.

To show chemical reactions between elements.

What is an endothermic reaction?

A reaction that produces light.

A reaction that occurs spontaneously.

What of the following is a characteristic of chemical reactions?

They involve the creation or breaking of chemical bonds.

They change the number of protons in an atom.

They can only occur in a laboratory setting.

What is the result of a single displacement reaction?

A compound and an element form a new compound and a different element.

A compound breaks down into simpler substances.

Two elements combine to form a compound.

Which of the following is true about endothermic reactions?

They absorb heat from the surroundings.

They do not involve energy changes.

They release heat into the surroundings.

They always result in a temperature decrease.

What is the main difference between a physical and chemical change?

A physical change alters the state of matter.

A physical change creates new substances.

A chemical change does not create new substances.

A chemical change alters the state of matter.

What does the term reactivity refer to in the context of the Periodic Table?

The ability of an element to combine chemically with other elements.

The distribution of electrons in an atom.

The temperature at which an atom melts.

The number of protons in an atom of an element.

What is the primary characteristic of a metalloid?

Properties of both metals and nonmetals.

Low conductivity and high reactivity.

High conductivity and high reactivity.

Always gaseous at room temperature.

What is the atomic number of an element?

The number of protons in the nucleus.

The number of neutrons in the nucleus.

The total number of protons and neutrons in the nucleus.

The total number of protons and electrons in an atom.

What is a warm front?

A boundary where warm air moves over cold air.

A boundary where cold air moves under warm air.

A boundary where warm air mixes with cold air.

Which of the following is a characteristic of a cold front?

Rapid weather changes and possibly thunderstorms.

Clouds forming in a layered pattern.

What is the primary difference between climate and weather?

Weather describes daily atmospheric conditions, while climate describes long-term patterns.

Weather and climate are terms for the same phenomena.

Climate describes daily atmospheric conditions, while weather describes yearly trends.

Climate and weather both describe daily conditions, but climate is more severe.

What happens at a stationary front?

Warm and cold air masses meet but do not move

Warm and cold air masses mix completely.

Cold air pushes rapidly under warm air.

Warm air rises rapidly over cold air.

Explain why coastal regions tend to have milder climates than inland areas.

The ocean moderates temperature fluctuations.

Coastal regions have higher altitudes.

Coastal regions receive more sunlight.

Coastal regions are closer to the equator.

How does altitude affect climate?

Higher altitudes are cooler because of decreased air pressure and thinner air.

Higher altitudes are warmer because they are closer to the Sun.

Altitude does not affect climate.

Higher altitudes are cooler because of increased pressure.

Describe the typical weather conditions when a warm front passes.

Gradual increase in cloudiness and light rain.

Clear skies and dry conditions.

Sudden and intense thunderstorms.

What role does vegetation play in influencing a region’s climate?

Vegetation can increase rainfall through transpiration.

Vegetation has no significant effect on climate.

Vegetation increases wind speeds by reducing surface resistance.

Vegetation can decrease temperatures by blocking sunlight.

What is the primary reason for the difference in temperature between the equator and the poles?

The equator receives more direct sunlight year round.

The poles are farther from the sun.

The equator is generally at a higher altitude than the poles.

The poles have more reflective surfaces, which cool the area.
