What happens to the air pressure in an area if the air temperature increases?
The air pressure will increase because the air particles are packed together.
The air pressure will decrease because the air particles are spread out.
The air pressure will remain the same because temperature does not affect the air particles.
The air pressure will remain the same because the hot air will travel to different areas.

Explanation:

The air pressure will decrease because the air particles are spread out.

That why hot air always travel upwards

an adaptation is a change or process by which an organism takes to be better suited for its environment. for example; migration is a behavioral adaptation, this is needed because birds are not built to last extremely cold climates. there are different adaptations because there are different species needing to adjust to different things, bears don't migrate; they hibernate.

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.
