Is humidity a physical change?
Changes in humidity are physical, NOT chemical, changes.
Is boiling of liquid air a physical or chemical change?
Physical
What can cause changes in relative humidity?
Either dehumidify (remove water vapour), rehumidify (add water vapour) - both at constant temperature, or raise temperature (which will lower relative humidity), or lower temperature (which will raise relative humidity).
How does temp and humidity change the speed of sound?
Yes, it affects the density of air and thus the speed of sound in air.
Is humidifiers putting moisture into the air a physical or chemical change?
It is physical
Is using a dehumidifier for moisture a chemical or physical change?
No. It is a physical change.
Is humidity a physical change?
Changes in humidity are physical, NOT chemical, changes.
How does air humidity change with the season?
humidity does not change the season the phases of the moon does
Is liquification of air a physical change?
Yes, liquification of air is a physical change.
Is reacts with air a chemical or physical change?
It is a chemical change.
Is water freezing to form ice a chemical or physical change?
well ! actually it is a very simple phenomenon.....because of the icy cold water, the air around it gets condensed when it comes close enough. consequently, the condensation causes the water vapors in the air to change into droplets that then appear on the surface of the container of that icy cold water...
Is heating the air in a balloon a chemical change or a physical change?
Physical.
Large water bodies often affect weather downwind by?
They can change air temp. and humidity in the air.
Why does heating of cold air reduce humidity?
Heating the air reduces the relative humidity. It doesn't change the amount of watervapor in the air. But warm air is able to hold more water vapor than cold air can, sowhen you heat the air, the air becomes 'less full' of water vapor, which means lowerrelative humidity.
Is Water vapor in the air an example of a physical or chemical change?
Physical change
Describe two ways the relative humidity of an air mass can change?
A change in temperature would most likely do that.
How can you change the environment for rusting metals?
You can reduce the air humidity is less oxidizing metals.
