individual particles do not expand, when a substance expands it is the dead space between the particles that expands and the particles begin to move around (assuming the substance was solid to begin with).
If a particle did expand it would loose cohesion and break apart (possibly creating an atomic reaction depending on how it was expanded)
What else can I help you with?
If you add heat energy to a substance what happens to the speed of the particle motion?
The particle speed increases.The energy increases; the speed increases.
What happens to particle movement as heat is added?
As heat is added to a substance, the particles in the substance gain kinetic energy and move faster. This increased movement causes the particles to vibrate and collide more frequently, leading to an expansion of the substance.
What happens when thermal energy is absorbed by a substance?
When thermal energy is absorbed the substance expands to some extent that is if it is a ball it becomes oblated to a very small extent as a balloon expands on blown with air , if it is a lengthy object the length becomes little longer.
What average amount of energy of motion of each particle of a substance is called?
The average amount of energy of motion of each particle of a substance is called kinetic energy. This energy is directly proportional to the temperature of the substance and is a measure of how fast the particles are moving.
What the average amount of energy of motion of each particle of a substance called?
The average amount of energy of motion of each particle of a substance is called kinetic energy. It is related to the speed and mass of the particles.
What happens to a substance or object when it is heated?
It expands.
What happens to the particle in a substance when it is cooled?
i. dont.know
What happens when to particles of a substance when it condenses?
Particle Movement decreases.
When a substance is cooled what happens to its particles how does cooling affect the volume of the substance?
When a substance is cooled, its particles lose kinetic energy and move more slowly, causing them to come closer together. This reduction in particle movement typically results in a decrease in the volume of the substance, as the particles occupy less space. In most cases, this leads to the substance contracting; however, exceptions exist, such as water, which expands upon freezing.
When a substance expands what happens to its mass?
When a substance expands, its mass remains constant, as mass is a measure of the amount of matter in an object and does not change with volume. However, the density of the substance decreases because density is defined as mass per unit volume. Thus, as the substance expands and its volume increases, the same mass is distributed over a larger volume, resulting in lower density.
What is the smallest particle a substance?
An atom is the smallest particle of a substance.
Change 3 explain what happens to the identity of a substance in a physical change 4- explain what causes a substance to change from one state to another 5- explan what happens to particle size?

What happens when railway tracks get hot?
railways expand on hot day because the particle are moving faster, which makes it need more space so it expands:)
When using the particle model of matter to describe what happens to the density of a substance when it cools?
The density of the substance becomes higher because of the particles slow down and move closer together when the substance cools.
If you add heat energy to a substance what happens to the speed of the particle motion?
The particle speed increases.The energy increases; the speed increases.
What substance expands when frozen?
water
What substance is a substance in which there is only one type of particle?
a pure substance
