Fill in the blanks: Condensation is the process in which particles in a combine into liquid droplets suspended in it. If the of the condensed droplets is considerably greater than that of the , the droplets will fall downward.
A puddle of water on a road loses one percent of its mass through evaporation. The water temperature remains constant throughout the evaporation.
Does the water heat or cool the air above it during the evaporation?
Does the water heat or cool the ground around it during the evaporation?
Droplets of water condense on a bathroom mirror that is at a lower temperature than the steam in the bathroom. The temperature of the water droplets remains constant throughout the condensation.
Does the condensation of water droplets heat or cool the mirror?
Does the condensation of water droplets heat or cool the air in the bathroom?
