Melting
Freezing
Evaporation
Sublimation
problema 5
pumili
Which of the following describes evaporation?
A liquid turning into a solid
A solid turning into a gas
A gas turning into a liquid
A liquid turning into a gas
problema 6
pumili
What is the term used to describe the amount of water vapor present in the air?
Precipitation
Evaporation
Dew
Humidity
problema 7
pumili
What is the difference between absolute humidity and relative humidity?
Absolute humidity measures the actual mass of water vapor in the air, while relative humidity compares it to the maximum amount the air can hold at a given temperature.
Absolute humidity refers to the liquid state of water, while relative humidity refers to the gaseous state.
Absolute humidity describes the air temperature, while relative humidity describes the air pressure.
Absolute humidity is measured in grams per liter, while relative humidity is measured in degrees Celsius.
problema 8
pumili
When the relative humidity of the air reaches 100%, what happens?
Water vapor evaporates into the air
Water vapor in the air condenses into liquid water
The air becomes dry
The temperature of the air increases
problema 9
pumili
What happens to the human body when the humidity is high on a hot day?
The body cools down faster because sweat evaporates quickly
The body may overheat because sweat does not evaporate as easily
The body stays cool because there is less sweat produced
The body absorbs more moisture from the air
problema 10
pumili
Why is it important to control humidity in manufacturing and storage processes?
To prevent condensation, which can damage products like food and electronics
To increase the evaporation rate for faster production
To maintain higher temperatures during storage
To increase the energy consumption of the manufacturing process
