Physical Science- Particle Theory Quiz

Matter is made up of particles. These particles can be atoms, molecules, or ions. They are the building blocks of all substances and are constantly in motion. Therefore, the correct answer is particles.

When the temperature is increased, the kinetic energy of the particles also increases. This increase in kinetic energy leads to an increase in the speed of the particles. As the particles gain more energy, they move faster and collide with each other more frequently, resulting in an overall increase in their speed.

In a pure substance, all particles are identical. This means that they have the same chemical composition and properties. Whether it is a solid, liquid, or gas, the particles that make up the substance are the same in terms of their atomic or molecular structure. This uniformity allows for consistent behavior and characteristics of the substance.

Pure substances are substances that are made of only one type of particle. This means that all the particles in a pure substance have the same chemical composition and properties. Examples of pure substances include elements like oxygen and gold, as well as compounds like water and salt. Pure substances can exist in both natural and man-made forms, but what defines them is the fact that they consist of a single type of particle.

Particles in ALL states of matter are constantly moving

The correct order of the spaces between particles in the states of matter is solids, liquids, gases. In solids, the particles are tightly packed together, resulting in the least amount of space between them. In liquids, the particles are still close together but have more space between them compared to solids. In gases, the particles are far apart, resulting in the largest amount of space between them.

Particles in gases, liquids, and solids refers to the fact that particles exist in all three states of matter. In gases, particles are widely spaced apart and move freely. In liquids, particles are closer together and can move past each other. In solids, particles are tightly packed and vibrate in place. This answer accurately describes the presence of particles in all three states of matter, highlighting their different arrangements and behaviors.
