Thermodynamics and Thermochemistry
Thermo Heat dynamics movement
energy
The
study of flow of heat or
any other kind
of energy into or out of a
system as it
undergoes a physical or chemical change
is thermodynamics
scope of thermodynamics
i It helps to predict feasibility of a
given process or a reaction under given
conditions of temperature pressure concentration
ii It also helps to determine the extent
to which a process or a reaction can
proceed before attainment of equilibrium
Limitations of thermodynamics
i It does not bother about time factor i e
it does not tell about rate speed of process
or reaction

Basic terms of thermodynamics
i System
A system is that part of universe which
is under observation
A system may have more than one
substances
ii Surroundings
The of universe which might be in
rest
position to exchange matter or energy
with the
system is called surrounding
iii Boundary Wall
The real or
imaginary surface which
separated system from surroundings is
boundary
, universe
system surroundings universe
Types of systems
i open system
surroundings
A system which exchanges energy as well as
matter from surroundings is called open system
open systems have
imaginary boundary
a glass of water
