Particle Theory Quiz #1

Matter is made up of particles. This is because matter refers to anything that has mass and occupies space, and particles are the smallest units of matter. These particles can be atoms, molecules, or ions, depending on the type of matter. 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. This is because the particles gain more energy and move faster, resulting in an overall increase in their speed.

In a pure substance, all the particles are identical. This means that they have the same chemical composition and properties. Whether it is a solid, liquid, or gas, the particles in a pure substance are made up of the same type of atoms or molecules. This uniformity allows for consistent behavior and characteristics of the substance.

Pure substances are substances that are made up 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, such as oxygen and gold, and compounds, such as water and salt. These substances are not mixed with any other substances and do not have any impurities. Therefore, the correct answer is "Are made of only one type of particle."

Particles in ALL states of matter are constantly moving

The answer is solids, liquids, gases. In solids, the particles are tightly packed together, resulting in the smallest spaces between them. In liquids, the particles have more freedom of movement but are still close together, so the spaces between them are larger than in solids but smaller than in gases. In gases, the particles are far apart and have the most freedom of movement, leading to the largest spaces between them.

The correct answer is "particles in gases, liquids and solids". This answer is correct because particles exist in all three states of matter: gases, liquids, and solids. In gases, particles are spread out and move freely. In liquids, particles are closer together and have more interaction. In solids, particles are tightly packed and vibrate in place. Therefore, particles can be found in all three states of matter.
