LATENT HEAT RELEASE
The release of energy when water vapor in the atmosphere condenses into liquid water.
APPLICATION This is important because when the water vapor
in the atmosphere condenses, the air will become warmer and this warm air will rise

LAW OF CONSERVATION OF MATTER
A law of nature stating that matter cannot be created or destroyed.
APPLICATION When paper is burned, it may seem to vanish but
no atoms are lost; the carbon and hydrogen that make up the paper combine with oxygen in the air to produce carbon dioxide and water vapor.

LD50
The lethal dose of a chemical that kills 50 percent of the individuals in a dose-response study.
APPLICATION This helps compare the harmful effects of
different chemicals

LEACH FIELD
A component of a septic system, make up of underground pipes laid out below the surface of the ground.
APPLICATION The pipes in the leach field contain small
perforations so the water can slowly seep out and spread.

LEACHATE
Liquid that contains elevate levels of pollutants as a result of having passed through municipal solid waste (MSW) or contaminated soil.
APPLICATION Leachate contains toxic chemicals that harm the
environment.

LEACHING
The transportation of dissolved molecules through the soil via groundwater.
APPLICATION The leached nitrates eventually settle in the
bottom sediments of oceans, lakes, and swamps.
