Hotel Service Unit 12 Q2 Quiz

Correct Answer:
B) The temperature of air as measured by a thermometer with a wetted bulb, which accounts for humidity

Explanation:
Wet bulb temperature reflects the cooling effect of evaporation and is influenced by the amount of moisture in the air. It is measured with a wetted thermometer bulb and helps in assessing humidity levels in air conditioning.

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

Explanation:
Relative humidity indicates how much water vapor is in the air compared to its maximum capacity at a certain temperature. This helps in maintaining comfortable and safe humidity levels in conditioned spaces.

Correct Answer:
B) A range of temperature and humidity conditions where occupants feel most comfortable

Explanation:
The comfort zone is the range of temperature and humidity levels that provide maximum comfort to occupants, preventing excessive dryness or humidity that could lead to discomfort.

Correct Answer:
C) To illustrate relationships between air properties, including temperature, humidity, and enthalpy

Explanation:
A psychrometric chart is a graphical tool that shows the relationships between various air properties, helping engineers analyze conditions like temperature, humidity, and energy content in air conditioning systems.

Correct Answer:
B) Relative humidity, dry bulb temperature, and wet bulb temperature

Explanation:
The psychrometric chart provides insights into various air properties, including relative humidity, dry bulb, and wet bulb temperatures, assisting in air conditioning design and efficiency assessments.

Correct Answer:
A) The temperature of the air measured without considering any moisture content

Explanation:
Dry bulb temperature is the standard air temperature measured by a regular thermometer, without factoring in humidity. It’s an essential measurement in determining overall air conditions in an air conditioning system.
