Condensation requires? a) the removal of energy b)the absorption of energy. c) no energy change.

Condensation requires the removal of energy.

Explanation:

Condensation is defined as the process in which gaseous particles get converted into liquid particles when temperature is decreased or pressure is increased.

During this process, energy is released by the particles. When vapor comes in contact with cooler particles, they loose some energy.

Condensation is an exothermic process because energy is lost during this process.

Hence, condensation requires the removal of energy.

aquifers are bounded above and below by impermeable rock. the driving force of groundwater movement in confined aquifers is pressure, rather than gravity.
