Define physical and chemical properties, provide three examples of each, discuss their reversibility, and explain the fundamental differences between them.

Physical properties are defined as the properties
which can be observed without changing its
chemical composition.
For example: color, volume, and molecular
weight.
Chemical properties are defined as the
properties which can be observed only after
changing chemical identity of the substance.
For example: reactivity, toxicity, and
flammability.
The fundamental differences between physical
and chemical properties are as follows:
Chemical properties are related to
chemical bonds of the substance while physical
properties are not.
In chemical properties, chemical identity of
substance changes while physical properties do
not have any change.
Chemical properties predict the reaction of
substance while physical properties only describe
the appearance of the substance.

If the water vapor content stays the same and the temperature drops, then the relative humidity increases. its vise versa.if the water vapor content stats the same and the temperature rises, the relative humidity decreases. so, yes, i'd say that temperature and humidity have a strong relationship.

The air is going to come out because of the low pressure.
