Assertion (A) Three states of matter are the result of balance between intermolecular forces and thermal energy of the molecules.
Reason (R) Intermolecular forces tend to keep the molecules together but thermal energy of molecules tends to keep them apart.
Assertion (A) At constant temperature, $p V v s V$ plot for real gases is not a straight line.
Reason (R) At high pressure all gases have $Z>1$ but at intermediate pressure most gases have $Z<1$.
Assertion (A) The temperature at which vapour pressure of a liquid is equal to the external pressure is called boiling temperature.
Reason (R) At high altitude atmospheric pressure is high.
