Question

A curve drawn at constant temperature is called an isotherm. This shows the relationship between:

• A. $P$ and $\frac{1}{V}$
• B. $PV$ and $V$
• C. $V$ and $\frac{1}{P}$
• D. $P$ and $V$

Answer 1

The correct option is D $P$ and $V$

A curve drawn at constant temperature is called an isotherm. This shows the relationship between pressure (P) and volume (V).
At constant temperature, the product of pressure and volume of a given amount of a gas is constant. This is known as Boyle's law.
The pressure (P) of a given mass of a gas varies inversely as its volume (V) at a constant temperature.
$P\propto \frac{1}{V}$
$PV=$ constant.
