tiny particles
When positively charged particles and negatively charged particles attract each other, the substance is electrically neutral. This is because the positive and negative charges balance each other out, resulting in no overall charge.
When a substance changes shape, the particles themselves do not change. They simply rearrange their positions relative to each other. In solids, the particles vibrate and shift slightly closer or farther apart. In liquids and gases, the particles move more freely and take the shape of their container.
Particles of one substance refer to the individual units that make up that specific substance. For example, in a sample of water, the particles would be the individual molecules of H2O. The properties of the substance are determined by the characteristics and interactions of its particles.
The total energy of motion in the particles of a substance is known as thermal energy. It represents the sum of the kinetic energies of all the particles in the substance. This energy is directly related to the temperature of the substance.
Density is a physical property of a substance that is determined by the mass of its particles and the volume they occupy. Each substance has a unique arrangement of atoms or molecules, which affects the packing and spacing of its particles. This unique arrangement results in each substance having a characteristic density.
The particles get attracted to each other, forming a solid.
Particles in a substance are able to flow over each other when the substance is in a liquid or gas state. In these states, the particles have enough energy to move around and slide past each other, allowing the substance to take the shape of its container.
When positively charged particles and negatively charged particles attract each other, the substance is electrically neutral. This is because the positive and negative charges balance each other out, resulting in no overall charge.
thermal energy
When a substance is heated, the kinetic energy of its particles increases. This leads to the particles moving faster and colliding more frequently with each other and the container they are in.
As a substance freezes, the particles slow down and lose kinetic energy. This leads to a more orderly arrangement of particles as they form a solid crystal lattice structure. The particles become locked into fixed positions, resulting in a decrease in overall movement and fluidity within the substance.
The average amount of energy of motion of each particle of a substance is known as its temperature. This is a measure of the average kinetic energy of the particles in the substance. At higher temperatures, particles have more kinetic energy and move faster.
When a substance changes shape, the particles themselves do not change. They simply rearrange their positions relative to each other. In solids, the particles vibrate and shift slightly closer or farther apart. In liquids and gases, the particles move more freely and take the shape of their container.
In an ideal gas, particles do not interact with each other. This means that they move independently and only interact through simple elastic collisions.
Temperature and thermal energy are related concepts but are distinct from each other. Temperature is a measure of the average kinetic energy of the particles in a substance, while thermal energy is the total kinetic energy of all the particles in a substance. In other words, temperature is a specific measurement of the average energy of particles, while thermal energy encompasses the total energy of all particles in a substance.
Temperature is a measure of the average energy of the particles in a substance. It indicates how fast the particles are moving within the substance.
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.
