Which of the following mixtures of gases at room temperature does not obey Dalton's law of partial pressure?

Which of the following statements is incorrect?
$1$. The property of liquid drops to have minimum surface area is called surface tension.
$2$. Surface tension of liquids decreases with rise in temperature.
$3$. The $SI$ unit of surface tension is $N \ m^{-1}$.
$4$. Magnitude of surface tension is less,when there is strong attractive force between the molecules.

Select the incorrect statement using the phase diagram of a substance.

Identify the correct statements from the following.
$I$. Glass is an extremely viscous liquid.
$II$. Increase in temperature decreases the surface tension of liquids.
$III$. Compressibility factor for an ideal gas is zero.

Consider the following statements:
Statement-$I$: If thermal energy is stronger than intermolecular forces,the substance prefers to be in a gaseous state.
Statement-$II$: At constant temperature,the density of an ideal gas is proportional to its pressure.
The correct answer is:

Choose the incorrect statement from the following:
