gas
at
27
°
C
be
cooled
in
23.
A

volume
of
20
litres
at
27
°
C
and
700
of
Hg
pressure
.
Calculate
the
volume
of

24.
The
pressure
of
a
gas
at
STP
is
tripled
and
the
temperature
raised
to
819
K.
What
is
the
final
volume
25.
A
gas
occupies
a
volume
of
500
cm
at
normal
temperature
.
At
what
temperature
will
the
volume
of
the
gas
be
reduced
by
20
%
of
its
original
volume
,
26.
On
heating
a
gas
,
it
was
found
that
its
volume
increases

the pressure remaining constant?
of its original volume,
of the gas?
pressure remaining constant?
by 50% and its pressure decreases to 60% of its original
volume. If the original temperature was -15°C, find the
temperature to which it was heated or cooled.
27. A given mass of a gas occupies 572 cm at 13°C and
725 mm of Hg pressure. What will be its volume at 24°C
and 792 mm of Hg pressure?
28. A flask having a volume of 250 mL and containing air
is heated to 100°C and sealed. The flask is cooled to
25°C and immersed in water and opened. What volume
of water will be drawn into the flask, assuming the
pressure to remain constant?
29. A volume of hydrogen measures 1 dm at 20°C and
0.5 atm pressure. What will be the volume at 10°C and
700 mm of Hg pressure?
30. An iron cylinder contains helium at a pressure of
250 kPa at 300 K. The cylinder can withstand a pressure
of 1 x 106 Pa. The room in which the cylinder is kept,
catches fire. Predict whether the cylinder will blow
up
before it melts or not. Melting point of iron cylinder is
1800 K.​
