Let's take the example of the balloon, which is maybe the easiest to visualize. An uninflated rubber balloon can contain a certain volume of gas at atmospheric pressure. You can see roughly what that volume is by pouring water into the balloon, then putting it under water, with the open end up, and letting the pressures equalize.
When you start to blow up the balloon, three things happen almost simultaneously.
1. You force more molecules into the available space, so a unit area (say 1 cm^2) of the balloon's surface will undergo increased bombardment by the gas molecules: this means the pressure on the surface increases. If it were a rigid container, that would be the end of the story: more molecules - more pressure. If the molecules pushed harder on the container, the container would push back harder on the molecules.
2. But a balloon isn't rigid: it's elastic, so it deforms when a force is applied to it. Since the force of the extra molecules is pushing in all directions, the balloon expands.
3. But that doesn't continue for long. As the balloon expands, and the rubber stretches, the forces in the walls of the balloon increase. After a short time, the forces tending to pull the balloon back to its original unstretched size balance out the increased forces exerted by the extra molecules, and everything reaches equilibrium. The pressure's higher, the balloon's bigger, and the rubber's stretched a bit.
And that continues until the balloon can't stretch any more. Same with tires and balls.
The subject of the actual pressure changes when blowing up a balloon is quite fascinating. Why does that floppy bit on the neck never expand? Why does a long balloon start to inflate near to your mouth instead of at the far end? I can't locate it right now, but if you search the Scientific American 'Amateur Scientist' archives you may be able to find an article published years ago on exactly these topics and many more.
I hope this is some assistance.
The particle theory of light, which suggests that light is made up of small particles called photons, was first proposed by Albert Einstein in 1905 to explain the photoelectric effect. This theory revolutionized our understanding of light and helped to explain phenomena that the wave theory of light could not account for. Today, the particle-wave duality of light is a fundamental concept in quantum mechanics.

An individual point particle in the standard model is described in string theory as a mode of vibration of a string. If for some reason the mode of vibration of the string changed, the particle would change to a different one.
It was Max Planck who used the particle theory of light.
Because the steam is rising to the top and putting pressure to the lid as the steam tries to escape.

Particle theory of light, proposed by Isaac Newton, views light as composed of discrete particles called photons. Wave theory of light, formulated by Thomas Young, describes light as a wave propagating through a medium. The wave theory better explains phenomena like interference and diffraction, while the particle theory accounts for aspects such as the photoelectric effect.
You can use the particle theory to help explain what happens when solutes dissolve. The particle theory states that there are spaces between all particles. This means that, in a sample of water, there are many water particles, but also many empty spaces. When you look at sugar. The sugar dissolves, the sugar particles separate and mix with the water particles.
Neither, try again.
The particle theory states that all matter is made up of tiny particles that are constantly moving. By applying this theory, we can explain everyday phenomena such as the expansion of gases when heated, the process of dissolving sugar in water, and the behavior of solids, liquids, and gases under different conditions. Essentially, the particle theory helps us understand the behavior of matter at a microscopic level.
The particle theory is called the "particle model" or "particle theory of matter." It proposes that all matter is composed of tiny particles that are in constant motion.
