EXPLORE
Boyle’s Law
The relationship between the volume and pressure of gases
at constant temperature was first stated by Robert Boyle
during the 16th century. He performed an experiment
wherein he trapped a fixed amount of air in the J-tube,
changed the pressure, and controlled the temperature, and
then, he observed its effect on the volume of the air inside
the J-tube.
He found out that as the pressure increases, the volume
d. Discussing new decreases. He finally concluded that the volume of a fixed
concepts and amount of gas is inversely proportional to its pressure at a
practicing new constant temperature. Then he proposed Boyle’s Law, which
skills # 1 states that the volume of a given mass of gas held at
constant temperature is inversely proportional to its
pressure.
Gas particles have a very weak intermolecular force of
attraction hence they move as far as possible from each
e. Discussing new other. They have the tendency to occupy all the spaces they
are contained in. If the pressure is increased, the volume will
concepts and
be decreased forcing the gas particles to move closer to one
practicing new another. The volume of a gas is inversely proportional to its
skills # 2 pressure, if the temperature and amount of a gas are held
constant.
The Boyle’s Law formula: P1V1=P2V2
Where:
V1 = initial volume
V2 = final volume
P1 = initial pressure
P2 = final pressure
