Question

The physical properties of a gas sample (such as amount, density, volume, pressure) are controlled by.....Group of answer choicesthe chemical identity of the gasthe temperature of the gasintermolecular forces

Answer 1

Intermolecular forces are those forces of attraction and repulsion that occur between the molecules of matter due, in general, to the presence and distribution of their electrons (polarity).

These forces are what determine the physical properties of substances. The temperature indicates greater movement and energy between the molecules, the pressure is the force exerted by these molecules per unit area and the volume is the space occupied by these molecules. All of this is governed by intermolecular forces that tell us how close or far apart the molecules will be.

So the answer will be Intermolecular forces. Last option.
