Essay conducive to safe
ntroduction:
In this experiment you resoluteness (1) determine whether Boyle’s Law applies to a
variety of gases (air) and (2) make a computation the gas constant,
R
, by determining the convolution of a
known amount of gas (H
2
) at a measured temperature and pressure.
Determination of Whether B
oyle’s Law Applies to Air
Boyle’s Law states that in quest of a fixed amount of gas
at stanch temperature, the pressure of the
elastic fluid will vary inversely with the book so that
P
1/
V
or
PV
= a firm (if
n
and
T
are
regular). To determine whether this relationship
holds in favor of a mixture of gases, the urgency of
a fixed amount of weather (which is a mixture of ga
ses) desire be measured as the volume of the weather
is varied while keeping the degree of heat of the air constant.
Determination of the Gas Constant,
R
The ~ model of perfection gas law arises from
several separate gas laws.
Boyle’s law
describes the indirect
relationship between pressure and volume,
P
1/
V
, with a view to a sample of gas at stated
temperature.
Charles’ law
describes the in the order of the signs relationshi
p between volume and temperature,
V
T
, for a sample of elastic fluid at
a constant pressure. The
Gay-Lussac jurisprudence
describes the direct
relationship between pre
ssure and temperature,
P
T
, for a sample of elastic fluid at constant
volume. Together these lead to
what’s referred to being of the kind which the
combined gas law
, used to recite the
properties of a given specimen of gas at two di
fferent sets of stipulations, labeled 1 and 2.

Another kinship between gas properties is
Avogadro’s Principle
. It states that according to the
case in which the urgency and temperature of
a gas are held resolute, the volume of the gas
is proportional to the nu
mber of...
