How do particles in matter change when a substance becomes hotter, cools down, or changes state? Be sure to include the three main points of a scientific explanation:

A scientific claim
Evidence to support the claim
Reasoning that connects the evidence to the claim

When a substance becomes hotter or cooler or change in state due to external change in energy, few changes takes place like:

Change in Interparticular force of attraction.Change in distance between voids.

When Energy is supplied:

A substance becomes more hot and changes it state i.e. Solid to liquid, or liquid to gas in normal conditions.

External energy is supplied.Average kinetic energy increases.The particles gets excited.They start moving farther increasing their Interparticular force of attraction.They makes some changes in shape & volume.

When Energy is taken away:

A substance becomes colder and changes it state i.e. gas to liquid, or liquid to solid in normal conditions.

Energy is taken away from the matter.Average kinetic energy decreases.The particles move closer to each other.The Interparticular force of attraction now increases because they are near to each other.This increases the density and make it compact.

Hello! data: p (pressure) = 1.25 atmv (volume) = ? (in l)t (temperature) = 298 kn (number of mols) = 0.900 molesr (gas constant) = 0.082 (atm*l/mol*k)apply the data to the clapeyron equation (ideal gas equation), see: i hope this . =)
