Question

Gases have higher density as compared to other states of matter.

• A. True
• B. False

Answer 1

The correct option is B False

• Three major states of matter are solid, liquid and gas.
• Gases have the lowest density as compared to solids and liquids.
• $\mathrm{Density}=\frac{\mathrm{Mass}}{\mathrm{Volume}}$
• Particles of a gas are in a constant random motion because they possess high kinetic energy and low intermolecular forces of attraction.
• For a gas, the mass contained in a given volume of a gas is very less.
• This is because the volume occupied by a gas is relatively larger by virtue of high kinetic energy.
• As density is inversely proportional to the volume, therefore large volume results in lower density, or as mass is directly proportional to density and mass contained in a given volume of gas is low, therefore density is also lower.
• For solids and liquids, the constituent particles are not as free to move as gases.
• Consequently, they occupy relatively lesser volume and mass contained per unit volume becomes high resulting in higher density.

Therefore, the given statement is false.
