As I push down the plunger on a sealed syringe, the pressure begins to
push back against me. Who's law is this?

Boyle's Law

Charles' Law

Gay-Lussac's Law

Avogadro's Law

Boyle's Law

Explanation:

This is a simple Boyle's law at work in this scenario.

Boyle's law is one of the gas law and it states that "The volume of a fixed mass of gas varies inversely as the pressure changes if temperature is constant".

This law was proposed by Robert Boyle.

This is clear cut practical of the Boyle's law.

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.
