Radioisotopes - Study guides, Class notes & Summaries

Biology 1023 Exam 1 Latest Version (Ch 16-19) Rated A+ What are radioisotopes known for? They are unstable elements that undergo transformation into other elements over time. They are used in radioactive dating, and the time required for a radioactive isotope to decay to half its original quantity is referred to as its half-life. Where are the majority of fossils of living organisms typically discovered? Sedimentary rock Which gas began accumulating in the atmosphere around 3 to...

First Law of Thermodynamics correct answers energy is neither created nor destroyed, may be converted from one form to another. Second Law of Thermodynamics correct answers when energy is changed from one form to another, some useful energy is degraded into lower quality energy (usually heat). Energy correct answers the ability to do work. Units of energy: joules, calories, kilocalories, British thermal units (BTUs), Kilowatt-hours (kWh) Power correct answers the rate of doing work (wor...
