Question

Match the following graphs with the laws they represent.

• A. Boyle's law
• B. Charle's law
• C. Ideal gas law

Answer 1

Boyle's law (isotherms) - It states that at constant temperature, the pressure exerted by a gas is inversely proportional to the volume of gas. The graph between V-P at constant temperature
is called an isotherm.

Charle's law (isobar)- It states that at constant pressure, the volume of a gas is directly proportional to the temperature. The graph between V-T at constant pressure is called an isobar.
Ideal gas law - It is a combination of Boyle's Law and Charles' Law. It shows the equation of a hypothetical ideal gas. Pressure and volume have an inverse relationship with each other but have a direct relationship with Temperature.
$\mathrm{PV}=\mathrm{nRT}$
is the ideal gas equation. Graph of PV vs P is as follows.
