Because they have different temperatures and when you measure an object's temperature, you measure the average kinetic energy of all the particles in the object.
No, the same amount of energy does not increase the temperature of different sized particles by the same amount. This is because temperature change depends on the mass of the particles; larger particles require more energy to achieve the same temperature change as smaller particles. Therefore, the specific heat capacity and the energy distribution among particles also influence how temperature changes with the energy input.
The average amount of energy of motion in the particles of a substance is known as its temperature. Temperature is a measure of the average kinetic energy of the particles in a substance. The higher the temperature, the greater the average kinetic energy of the particles.
Solid particles have the least kinetic energy, followed by liquid particles, and then gas particles. In solids, particles vibrate in fixed positions with minimal movement, while in liquids, particles have more energy and can move around each other. Gas particles have the highest kinetic energy, as they move rapidly and have more freedom of motion.
Temperature is the measure of average energy of motion of particles within a substance because temperature reflects the amount of kinetic energy present in the particles. As particles move faster, they have higher kinetic energy. By measuring the average kinetic energy of particles, temperature provides a standardized way to compare the thermal energy of different substances.
It can vary; a plasma can have a temperature of a few thousand degrees, or millions, or even billions of degrees - in each case, the amount of energy will be different. Of course, the amount of energy will also depend on the amount of plasma we are talking about.
The amount of energy an object contains and the speed at which its particles move are related to its temperature. Energy can be stored in different forms within the object, such as kinetic energy from particle movement or potential energy stored in bonds between particles. As particles move faster, they usually have higher energy levels, which in turn contributes to the overall energy of the object.
Relative to liquids and gasses, they have the least amount of energy. In terms of the actual particles themselves, the amount of energy they possess depends on their structure and composition along with the temperature.
In a system of 2 particles in a box, the energy levels are quantized, meaning they can only have specific values. The energy levels are determined by the size of the box and the mass of the particles. The particles can occupy different energy levels, with each level corresponding to a specific amount of energy. The energy levels are spaced apart evenly, and the particles cannot have energy levels in between these quantized values.
The average amount of energy of motion in the particles of a substance is known as temperature. Temperature is a measure of the average kinetic energy of the particles in a substance. Particles with higher kinetic energy move faster and collide more frequently, resulting in a higher temperature.
This energy is the activation energy.
Atoms
The average amount of energy of motion (also known as kinetic energy) in the particles of a substance (atoms and molecules) is measured by the temperature of that substance. More energy will produce a higher temperature.
