35 flashcard

Front

What is the purpose of the generalized comfort chart?

Back

To determine combinations of temperature and humidity to produce comfort in summer and winter.

Front

What process in the human body produces heat through perspiration?

Back

Evaporation.

Front

What is the dew-point temperature?

Back

The temperature at which moisture begins to condense out of the air.

Front

True or False: The rate at which water evaporates from the wick on the wet-bulb thermometer is determined by the moisture content of the surrounding air.

Back

True.

Front

What does the dry-bulb temperature represent?

Back

The sensible heat level of the air.

Front

Define 'sensible heat'.

Back

Sensible heat is the heat exchanged by a thermodynamic system that results in a temperature change.

Front

What is 'latent heat'?

Back

Latent heat is the heat absorbed or released during a phase change of a substance without a change in temperature.

Front

Explain the concept of 'humidity'.

Back

Humidity is the amount of water vapor present in the air, usually expressed as a percentage.

Front

What is the relationship between temperature and humidity in comfort levels?

Back

Higher humidity levels can make temperatures feel warmer, while lower humidity can make temperatures feel cooler.

Front

What is the significance of the wet-bulb temperature?

Back

The wet-bulb temperature indicates the amount of moisture in the air and is used to assess comfort levels.
