Question

Watch the video to determine which of the following relationships correctly depict the relationship between pressure and volume for a fixed amount of gas at constant temperature according to Boyle’s law.
A. PV∝ P
B.V∝ 1P
C. P∝ 1V
D. PV∝ V
E. P∝ V
F. V∝ P

Answer 1

Answer : The correct options are,

(B) $V\propto \frac{1}{P}$

(C) $P\propto \frac{1}{V}$

Explanation :

Boyle's Law : It is defined as the pressure of the gas is inversely proportional to the volume of the gas at constant temperature and number of moles.

$P\propto \frac{1}{V}$

or,

$V\propto \frac{1}{P}$

The relation between the pressure and volume of two gases are:

$P_1V_1=P_2V_2$

where,

$P_1$ = initial pressure of gas

$P_2$ = final pressure of gas

$V_1$ = initial volume of gas

$V_2$ = final volume of gas
