low-throughput economy
Economy based on working with nature by (1) recycling and reusing discarded matter, (2) preventing pollution, (3) conserving matter and energy resources by reducing unnecessary waste and use, (4) not degrading renewable resources, (5) building things that are easy to recycle, reuse, and repair, (6) not allowing population size to exceed the carrying capacity of the environment, and (7) preserving biodiversity. See environmental worldview. Compare high-throughput economy, matter-recycling economy.
Subject:
low-quality matter
Matter that is dilute or dispersed or contains a low concentration of a useful resource. Compare high-quality matter.
Subject:
low-quality energy
Energy that is dispersed and has little ability to do useful work. An example is low-temperature heat. Compare high-quality energy.
Subject:
law of conservation of matter
In any physical or chemical change, matter is neither created nor destroyed but merely changed from one form to another; in physical and chemical changes, existing atoms are rearranged into different spatial patterns (physical changes) or different combinations (chemical changes).
Subject:
law of conservation of energy
See first law of thermodynamics.
Subject:
kinetic energy
Energy that matter has because of its mass and speed or velocity. Compare potential energy.
Subject:
kilocalorie (kcal)
Unit of energy equal to 1,000 calories. See calorie.
Subject:
isotopes
Two or more forms of a chemical element that have the same number of protons but different mass numbers because they have different numbers of neutrons in their nuclei.
Subject:
ionizing radiation
Fast-moving alpha or beta particles or high-energy radiation (gamma rays) emitted by radioisotopes. They have enough energy to dislodge one or more electrons from atoms they hit, forming charged ions in tissue that can react with and damage living tissue. Compare nonionizing radiation.
