Document Summary

Law of conservation of matter can be illustrated by three equations, applied to an enclosed, isolated system. (cid:1835)(cid:1840)(cid:1842)(cid:1847)(cid:1846)(cid:3404)(cid:1841)(cid:1847)(cid:1846)(cid:1842)(cid:1847)(cid:1846) (1) (cid:1827)(cid:1829)(cid:1829)(cid:1847)(cid:1839)(cid:1847)(cid:1838)(cid:1827)(cid:1846)(cid:1835)(cid:1841)(cid:1840)(cid:3404)(cid:1835)(cid:1840)(cid:1842)(cid:1847)(cid:1846)(cid:3398)(cid:1841)(cid:1847)(cid:1846)(cid:1842)(cid:1847)(cid:1846) (2) (cid:1827)(cid:1829)(cid:1829)(cid:1847)(cid:1839)(cid:1847)(cid:1838)(cid:1827)(cid:1846)(cid:1835)(cid:1841)(cid:1840) (cid:1844)(cid:1827)(cid:1846)(cid:1831)(cid:3404)(cid:1835)(cid:1840)(cid:1842)(cid:1847)(cid:1846) (cid:1844)(cid:1827)(cid:1846)(cid:1831)(cid:3398) (cid:1841)(cid:1847)(cid:1846)(cid:1842)(cid:1847)(cid:1846) (cid:1844)(cid:1827)(cid:1846)(cid:1831) (3) A substance that enters the region has three possible fates: some of it may leave the region unchanged, some of it may accumulate within the boundary, some of it may be converted to some other substance. The decay term does not imply a violation of the law. Atoms are conserved, but there is no similar constraint on the chemical reactions, which may change one substance into another. When there is no accumulation in a system, it will be called steady state. For unsteady state, the rate of accumulation is changing with time. When a substance is conserved within a region, there is no radioactive decay, bacterial decomposition, or chemical reaction occurring. 4. 1. 1 steady-state conservative systems (cid:1835)(cid:1840)(cid:1842)(cid:1847)(cid:1846) (cid:1844)(cid:1827)(cid:1846)(cid:1831)(cid:3404)(cid:1841)(cid:1847)(cid:1846)(cid:1842)(cid:1847)(cid:1846) (cid:1844)(cid:1827)(cid:1846)(cid:1831) (4)
