what does the law of conservation of energy state?
Energy can be neither created nor destroyed, but transformed and transferred
What is an open system?
A system that can exchange energy and matter
what is a closed system
a system that can exchange energy but not matter
what is an isolated system
a system that cannot exchange energy or matter
radiation
an energy transform where atoms and molecules give of energy in the form of electromagnetic waves
nuclear decay
the chance to an atom due to the emission of particles or radiation
nuclear fission
a heavier nucleus is split into 2 smaller, lighter nuclei with a release of energy
nuclear fusion
2 very small nuclei combine/ fuse to form a slightly larger nucleus
