Hotel Service Unit 12 Q1 Quiz

Correct Answer:
B) The temperature at which air becomes fully saturated with water vapor, causing condensation

Explanation:
The dew point is the temperature at which the air reaches saturation, meaning it can no longer hold all the water vapor, leading to condensation. This is crucial in preventing moisture buildup in air-conditioned spaces.

Correct Answer:
B) To control temperature, providing a comfortable environment

Explanation:
A primary function of air conditioning is to control the temperature, creating a comfortable environment by either cooling or heating the air as needed.

Correct Answer:
C) It decreases

Explanation:
As temperature rises, the air’s capacity to hold moisture increases, so relative humidity decreases if the amount of water vapor (absolute humidity) remains the same.

Correct Answer:
B) Controlling humidity to prevent excessive dryness or dampness

Explanation:
Air conditioning systems control humidity by either removing moisture to reduce dampness or adding moisture to prevent dryness, which is essential for maintaining indoor comfort and preventing damage to materials.

Correct Answer:
A) By filtering out dust, allergens, and pollutants

Explanation:
Air conditioning systems typically include filters that trap dust, allergens, and other airborne particles, improving air quality for occupants.

Correct Answer:
C) It indicates the temperature at which moisture will start condensing, which is essential to avoid humidity-related issues like mold

Explanation:
Knowing the dew point helps prevent condensation and moisture-related issues, which are important for maintaining comfort and air quality in air-conditioned spaces.

Correct Answer:
B) The total amount of water vapor present in a specific volume of air, regardless of temperature

Explanation:
Absolute humidity is the total mass of water vapor per unit volume of air, measured in grams per cubic meter (g/m³). It does not depend on temperature.

Correct Answer:
B) The amount of water vapor in the air relative to the maximum amount that could be held at a specific temperature, expressed as a percentage

Explanation:
Relative humidity measures how much water vapor the air holds compared to its maximum capacity at a given temperature. High relative humidity means the air is near saturation.
