Soil carbon stocks Carbon stored in soil
Soil pollution Presence of substances in soil at concentrations greater than
their usual levels that affect biotic and abiotic component of environment
significantly
Solubility Ability of a substance that can be dissolved in a given amount of a liquid
Sound energy Form of energy generated when object vibrate
Sound power Rate at which sound energy is transmitted, emitted, received, or
reflected per unit time
Source reduction (in the context of solid waste) Reducing the quantity of waste
at source
Source separation (in the context of solid waste) Segregating wastes into various
components at the point of generation
Speed Rate of change of position without considering direction. It is scalar absolute value of velocity
Spherical wave Wave created by a sound source that radiates the energy equally
in all directions
Standard heat of combustion Amount of heat evolved at one atmosphere pressure
and at 25 °C when one mole of a substance is burned in excess oxygen
Statics Specialization of mechanics that deals with bodies at rest as well as forces
in equilibrium
Stationary source (in the context of air pollution) Non-mobile source (e.g.,
power plant, refinery, manufacturing facility)
Step-down transformer Transformer in which output electric potential difference
is less than that of the input
Step-up transformer Transformer in which the output electric potential difference
is greater than its input
Stoichiometry Collective term for the quantitative relationship between the numbers of atoms/molecules/ions, the masses, and the numbers of moles
Storage Temporary holding of material
Storage containers Vessels used to contain material for storage
Storm surge Coastal flood on coasts and lake shores caused by wind
Strain It is the ratio of the alteration in size/shape to the original size/shape. Strain
is a dimensionless number
Stress The ratio of internal force generated when a body is deformed to area on
which this force acts
Structural formula Graphical representation of arrangement of atoms in a
chemical
Subclinical disease Stage in some diseases before appearance of symptoms
Sulfur dioxide (SO 2 ) Gas comprising one sulfur atom and two oxygen atoms
Surface runoff Water that flows over the land surface to the nearest surface stream
Surface tension Elastic tendency of a fluid surface
Surgery Treatment of injuries or disorders of the body is treated by incision or
manipulation with help of instruments
Syndrome Group of symptoms that consistently occurs together, and characterizes
a particular abnormality/condition
