the particle theory states that all matter in the world or universe is made up of particles. so the answers to your question is that when an object melts that particles in that object will start to move more rapidly, having more collisions and therefor the object will expands......... hope that helps
In the particle theory of matter, a pure substance is made up of only one type of particle, either an element or a compound. A mixture, on the other hand, is made up of two or more different substances physically combined together, with each substance retaining its distinct properties.
In a saturated solution, the solvent has dissolved the maximum amount of solute it can hold at a given temperature. In an unsaturated solution, the solvent has not dissolved the maximum amount of solute it can hold at that temperature, meaning more solute could still be dissolved.
You could use spectroscopy to analyze the light emitted by the sun to look for the characteristic spectral lines of platinum. If you detect these specific spectral lines in the sun's spectrum, it would support the theory. Conversely, if you do not find these lines in the sun's spectrum, it would provide evidence against the theory.
Matter is anything that has mass and can take up space.The Particle Theory of Matter:1. Matter is made up of tiny particles (Atoms & Molecules)2. Particles of Matter are in constant motion.3. Particles of Matter are held together by very strong electric forces4. There are empty spaces between the particles of matter that are very large compared to the particles themselves.5. Each substance has unique particles that are different from the particles of other substances6. Temperature affects the speed of the particles. The higher the temperature, the faster the speed of the particles
Water is a good solvent due to its polar nature. The partial charges on the oxygen and hydrogen atoms allow water molecules to interact with solute molecules through hydrogen bonding, breaking them apart and dispersing them evenly. This makes it effective at dissolving a wide range of solutes.

Solids do not flow because particles in a solid are so close together and their forces of attraction are so strong that they cannot flow past one another. If you have a 8th grade Science & Technology Textbook, you can look at page 89 in the second paragraph (Explaining Flow Using Particle Theory) and 2nd sentence, which is your answer that you are looking for (Using the particle theory explain why solids do not flow?)
Diathesis-stress Theory
According to particle theory, a solid can be melted by increasing the temperature, which adds energy to the particles. As the temperature rises, the particles vibrate more vigorously, overcoming the forces that hold them in fixed positions. Once enough energy is supplied, these particles can break free from their organized structure, transitioning the solid into a liquid state. This process illustrates the changes in particle movement and arrangement during melting.

Explain the advantages and disadvantages of Best Buy's different employee programs using Maslows hierarchy of needs theory reinforcement theory and expectancy theory?
Evaporation occurs when water molecules at the surface of a liquid gain enough kinetic energy to break free from the liquid's surface and become a gas. This process is explained by particle theory as the higher-energy water molecules break away from the liquid and escape into the air, leaving behind lower-energy molecules, which cools the remaining liquid.
we describe air by answering it's properties
As a solution becomes saturated, more solute particles are added than can be dissolved by the solvent. The solvent molecules surround the solute particles, preventing further dissolution. At saturation, the rate of solute particles leaving the solution equals the rate of solute particles entering it, maintaining a dynamic equilibrium. This creates a maximum concentration of solute that the solvent can hold at a given temperature.

For many applications, the Particle Theory is an adequate working model. It is known to no longer be apply in many circumstances. So pragmatism wins the day.Similarly, 25/8 is an adequate approximation of Pi for most 'back of the envelope' calculations, even though it is known to be inexact.
Collision rate can be determined from Langevin theory by calculating the frequency of collisions between the particle and surrounding particles. This can be done by considering the particle's diffusion coefficient, the size of the particle, and the density of the surrounding medium. By using these parameters, one can estimate the collision rate based on the Langevin equation.
