Boyle's Law
Purpose: Verify Boyle's Law by measurement the pressure of the
atmosphere. Boyle also came up with a mathematical relationship
to help us figure out the pressure or volume of a gas in an enclosed
space: No matter how the pressure or volume in the gas vessel is
changed, the product of gas pressure multiplied by the volume of
the vessel is always equal to a constant number.
Boyle's Law states that as the volume decreases in a vessel
containing gas, the pressure inside the vessel increases - and vice
versa, as the volume increases, the pressure decreases.The
temperature is steady
Boyle's law is one of the laws of gases on the basis of which the
ideal gas law is derived. It states that the volume of a
specified amount of gas is inversely proportional to the pressure
applied to it when its temperature is constant. ... "At
a constant temperature, when the pressure of a certain amount of a
gas changes, the volume is inversely proportional to the change in
pressure.“
Apparatus: Glass tube containing mercury as shown.
Theory: The equation used to find the atmosphere pressure is:
, Where C&K = constants
h & L the length as shown in fig (1)
. B =atmosphere pressure.
Procedure:
1-Keep the mercury levels X and Y in the same position. Record
the scale reading of these levels and also the scale reading of (A),
the inside of the closed end of the tube (AB). This is the balance
point (i.e. X=Y).
2.Rising the tube CD (above the balance point), and record
the scale reading of X and Y levels.
3. Take about four sets of reading over the balance point.
4. Now, lowering the tube CD below the balance point, and
record the scale reading of X and Y levels.
5. Take about four sets of reading below the balance point.
