I think made up of particles that are far apart from each other, having both indefinite shape and indefinite volume describes the characteristics of a gas.

Answer from: trent1002brown

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

Explanation:

There are 4 states of matter:

Solid state: In this state of matter, the particles are closely packed and they do not have any space between them. Thus, this state of matter has the highest intermolecular forces of attraction between them.

This state have a definite shape and volume.

Liquid state: In this state of matter, the particles are present in random and irregular pattern. The particles are closely arranged but they can move from one place to another. The intermolecular forces between the particles are less as compared to the solid state.

This state have a definite volume but does not have a fixed shape and they can take up the shape of container in which they are kept.

Gaseous state: In this state, the particles are loosely arranged and have a lot of space between them. Thus, this state of matter has the lowest intermolecular forces of attraction between them.

This state have indefinite volume as well as shape. It can take up the volume and shape of the container in which they are kept.

Plasma state: In this state of matter, a hot ionized gas consisting of equal number of positively charged ions and negatively charged electrons are present.

This state have indefinite volume as well as shape.

Hence, the correct statement is made up of particles that are far apart from each other, having both indefinite shape and indefinite volume

Answer from: Quest

hey there!

boiling point is the temperature at which the vapor pressure of the liquid equals atmospheric pressure. the vapor pressure of solvent molecules is decreased when a solute is added, so a higher temperature is required to increase the number of solvent molecules in the gas phase above the liquid.

at the freezing point, the vapor pressures of the solid and liquid are equal; a lower temperature is needed to reduce the number of solvent particles above the liquid.

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".
