The equation CO2 = P × S × E × C shows how the total amount of carbon dioxide emissions on Earth (CO2) is calculated. The number of people (P) is multiplied by the services, like electricity, that the people use (S). This is multiplied by the energy needed for each service (E) and then by the amount of carbon dioxide released for each unit of energy (C). In order for the total emissions to be 0, why must one of the variables on the right side of the equation be 0? Realistically, why is C the only variable that can become 0?

right

explanation:

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.
