An object with more particles has more thermal energy because there are more particles vibrating and moving, which contributes to the overall thermal energy of the object. The more particles there are, the more kinetic energy is present in the system, leading to a higher overall thermal energy.
The amount of particles in an object affects temperature by influencing the object's internal energy. More particles typically result in a higher internal energy, leading to a higher temperature. Conversely, fewer particles usually result in lower internal energy and a lower temperature.

Sound can still travel through fewer particles because it propagates by causing the particles to vibrate and pass the energy along. Even in sparser mediums, such as in outer space, sound can still travel through the few particles present, but it may not propagate as effectively as in denser mediums like air or water.
As air particles get colder, they lose kinetic energy and move more slowly. This causes the pressure inside the ball to decrease because there are fewer collisions between the particles and the walls of the ball.
Changing the initial mass of the copper will affect the total amount of energy the copper has. More mass means more particles requiring energy for movement and vibration, resulting in a higher total energy. Conversely, less mass will result in lower total energy due to fewer particles needing energy for motion.

The movement is random, but there is a net movement from regions where there are lots of particles to ones where there are fewer particles.

The state with the least number of particles in a certain volume would be a gas, as the particles in a gas are more spread out and have more kinetic energy compared to particles in liquids or solids. This results in fewer particles occupying a specific volume in a gas compared to a liquid or solid.

When particles condense, they come together to form a denser phase, such as a liquid from a gas or a solid from a gas. This process releases heat energy and allows the particles to move closer together, resulting in a decrease in volume.
When there are fewer gas particles, the pressure of the gas decreases because there are fewer particles colliding with the walls of the container. The volume of the gas may also increase slightly if the gas particles are able to spread out more freely. The temperature of the gas remains constant unless it is actively changed.
It has a high temperature but it is not hot. Temperature (kinetic energy) and hot (thermal energy - a way of transferring energy between objects) are not the same thing. Temperature is the average velocity of particles, which in the thermosphere is quite high, but they are far less dense than in the troposphere, which means that they collide much less often and those fewer collision mean less energy transfer (less heat).
The thermosphere has the highest temperature of all atmospheric layers due to its absorption of high-energy solar radiation, particularly ultraviolet and X-ray radiation. This energy excites molecules and atoms, causing them to increase in kinetic energy, which translates to higher temperatures. Additionally, the thermosphere is less dense, meaning there are fewer particles to absorb and distribute heat, allowing temperatures to rise dramatically without a corresponding increase in thermal energy transfer.
