Question

What are the characteristics of a substance in the gas phase?

made up of particles packed closely together, having both definite shape and definite volume

made up of particles packed relatively close together, having an indefinite shape but a definite volume

made up of particles that are far apart from each other, having both indefinite shape and indefinite volume

made up of positively charged particles and negatively charged electrons, having indefinite shape and indefinite volume

Answer 1

The characteristics of a substance in the Gas phase are that they are made up of particles that are far apart from each other, having both indefinite shape and indefinite volume.

Answer 2

Answer:  made up of particles that are far apart from each other, having both indefinite shape and indefinite volume

Explanation:  The substances present in the gas phase are very far apart from each other. They have the maximum randomness or entropy.

These particles do not conatin any kind of charged ions so they do not held together by any electrostatic force of attraction.

Due to such randomness, they have indefinite volume and shape.

The collision between the particles of the gas is maximum thus they are known to have maximum kinetic energy.
