Systemic disease Ailment that affects entire body
Tailings Residues from ore processing
Tangential stress Stress generated when a force is applied parallel to surface of a
body
Target organ An organ that is specifically affected by a toxic chemical
Temperature Relative hotness or coldness of an object
Temperature gradient Rate of change of temperature in a particular location
Terminal disease Disease that cannot be satisfactorily treated and is likely to result
in the death
Thermal energy Thermal energy is internal energy in a system in a state of thermodynamic equilibrium due to its temperature
Thermal pollution The discharge of liquid with higher temperature into natural
waters that would cause harm to environment
Thermal treatment Use of elevated temperatures to treat waste
Thermocline Transition layer between warmer mixed water and cooler water in
surface water body

Toxicity Extent to which a matter can damage an organism
Toxicology Specialty of science that deals with study of undesirable effects that
occur in living being owing to chemicals
Transcytosis Transcellular transport of macromolecule across cell
Transistor Device used to regulate electric current or potential difference, which
acts as a gate for electronic signals
Urbanization Process of the transformation of land to cities
Valence (or valance number) Number of electrons present in outermost orbit (or
shell) of an atom
Valency Measure of its combining power with other atoms when it forms
molecules
Vector (in the context of epidemiology) Living organisms that can transmit infection among humans, or from animals to humans
Vector (in the context of physics) Physical quantity that has magnitude and direction but not position
Velocity The rate of change of displacement with respect to frame of reference
Venereology Branch of medicine that deals with disorders transmitted through
sexual contact
Vermi-compost Composting process that uses earthworms
Very preterm birth A newborn with the gestation period is less than 32 weeks
Virtual image Image appears to be formed when light rays originate from object
diverge but cannot be projected onto a screen
