When a gas occupies a smaller volume, it exerts a higher pressure; when it occupies a larger volume, it exerts a lower pressure (assuming the amount of gas and the temperature do not change). Since
P and V are inversely proportional
, a graph of 1/P vs. V is linear.
What’s the relationship between pressure and volume?
It is summarized in the statement now known as Boyle’s law:
The volume of a given amount of gas held at constant temperature is inversely proportional to the pressure under
which it is measured.
What is the relationship between P and V chemistry?
This empirical relation, formulated by the physicist Robert Boyle in 1662, states that the pressure (p) of a given quantity of gas varies inversely with its volume (v) at constant temperature; i.e., in equation form,
pv = k, a constant
. The relationship was also discovered by the French physicist Edme Mariotte (1676).
What is the relationship between temperature and pressure direct or inverse?
The
pressure of a given amount of gas is directly proportional to its absolute temperature
, provided that the volume does not change (Amontons’s law). The volume of a given gas sample is directly proportional to its absolute temperature at constant pressure (Charles’s law).
As a conclusion,
P is directly proportional to n and T
and inversely proportional to V .
What is P1 V1 P2 V2?
The relationship for Boyle’s Law can be expressed as follows:
P1V1 = P2V2
, where P1 and V1 are the initial pressure and volume values, and P2 and V2 are the values of the pressure and volume of the gas after change.
Is V vs P direct or indirect?
vV ^P ^V vP the relationship is inverse
. Pressure and temperature will both increase or decrease simultaneously as long as the volume is held constant. Therefore if temperature were to double the pressure would likewise double.
