Here is a very simple trivia quiz on air pressure that we have brought for you. Do you know air pressure is also called atmospheric pressure? The air around us has some weight and presses against everything it touches. This pressure is called air pressure. The questions in this quiz are not that hard, and one with even a little knowledge about air and air pressure can attempt this quiz. So, are you ready for this quiz? Wish you the best of luck. Let's go for it now!

• 1.

### Air Pressure is measured with ________.

• A.

Thermometer

• B.

Lactometer

• C.

Barometer

• D.

None of these

C. Barometer
Explanation
Air pressure is measured with a barometer. A barometer is an instrument used to measure atmospheric pressure. It consists of a glass tube filled with mercury or a liquid, with one end sealed and the other end open to the atmosphere. As the air pressure changes, it causes the liquid level in the tube to rise or fall. By measuring this change in liquid level, the air pressure can be determined. A thermometer is used to measure temperature, and a lactometer is used to measure the density of milk. Therefore, the correct instrument for measuring air pressure is a barometer.

### What are the factors that affect air pressure? (Select multiple options)

• A.

Altitude

• B.

Distance from Large Body of Water

• C.

Humidity

• D.

Temperature

• E.

Latitude

• F.

Presence of Mountain Ranges

• G.

Ocean Currents

• H.

Prevailing Winds

• I.

Precipitation

A. Altitude
C. Humidity
D. Temperature
Explanation
Altitude, humidity, and temperature are factors that affect air pressure. As altitude increases, air pressure decreases due to the decrease in the weight of the air column above. Humidity affects air pressure because water vapor is lighter than dry air, so an increase in humidity decreases air pressure. Temperature also affects air pressure as warm air expands and becomes less dense, resulting in lower pressure.

### Warm air is lighter than cold air.

• A.

True

• B.

False

A. True
Explanation
Warm air is lighter than cold air because warm air molecules have more energy and are therefore more spread out, resulting in a lower density. This lower density causes warm air to rise and cold air to sink, leading to the phenomenon of convection and the formation of weather patterns.

### When it is raining, the air has high pressure.

• A.

True

• B.

False

B. False
Explanation
When it is raining, the air actually has low pressure. This is because rain is typically associated with low-pressure weather systems, where warm air rises and cools, leading to condensation and precipitation. High-pressure systems are generally associated with clear and dry weather conditions. Therefore, the statement "When it is raining, the air has high pressure" is false.

### Cold air stays high in the air, while warm air stays low in the air.

• A.

True

• B.

False

B. False
Explanation
The statement is false because warm air rises and cold air sinks. This is due to the differences in density between warm and cold air. When air is heated, its molecules move faster and spread out, causing the air to become less dense and rise. Conversely, when air is cooled, its molecules slow down and come closer together, making the air more dense and causing it to sink. This phenomenon is responsible for the formation of weather patterns and the circulation of air in the atmosphere.

### How do meteorologists describe the atmospheric pressure?

• A.

• B.

How low the mercury drops.

• C.

How high the mercury rises.

• D.

All of the above

C. How high the mercury rises.
Explanation
Meteorologists describe the atmospheric pressure by measuring how high the mercury rises in a barometer. The mercury in the barometer is pushed up by the air pressure exerted on it, and this rise in the mercury column is used to determine the atmospheric pressure. This method has been widely used for centuries to measure and describe atmospheric pressure.

### Air with high pressure is always cold.

• A.

True

• B.

False

B. False
Explanation
The statement that air with high pressure is always cold is false. While it is true that high pressure systems are generally associated with cooler temperatures, this is not always the case. High pressure systems can also bring warm and sunny weather. The temperature of the air is determined by various factors such as the source region, air mass characteristics, and atmospheric conditions, not solely by the pressure. Therefore, it is incorrect to assume that air with high pressure is always cold.

### When force atoms and molecules strike a surface, they exert.

• A.

True

• B.

False

A. True
Explanation
When force atoms and molecules strike a surface, they exert a force on that surface. This force is known as the normal force and it acts perpendicular to the surface. It is a result of the interaction between the atoms and molecules of the surface and the atoms and molecules of the object applying the force. Therefore, the statement "When force atoms and molecules strike a surface, they exert" is true.

### Temperature and air pressure are _______.

• A.

Closely related

• B.

Opposite

• C.

Not related

• D.

Are the same thing

A. Closely related
Explanation
Temperature and air pressure are closely related because changes in air pressure can cause changes in temperature and vice versa. When air pressure decreases, the air molecules spread out and the temperature decreases. Conversely, when air pressure increases, the air molecules become more compressed and the temperature increases. This relationship between temperature and air pressure is known as the ideal gas law, which states that temperature and pressure are directly proportional to each other when the volume and number of gas molecules remain constant.

### Air becomes _________ on high altitude.

• A.

Thicker

• B.

Warmer

• C.

Thinner

• D.

None of these

C. Thinner
Explanation
At higher altitudes, the air pressure decreases, resulting in lower density of air molecules. This decrease in density causes the air to become thinner. Therefore, the correct answer is "Thinner".
