How does heat affect particles?
heat affects particles by making them move about faster and vibrate more passing more energy to other particles.
How do particles moves as energy is transferred through a sound wave?
It depends on what medium it is in. If it is in a solid medium, the particles will be closely together, or vibrating. If it is in a liquid, the particles will be spreaded out and moving slowly. If it is in a gas, the particles will be in moving rapidly.
What do the particles of a solid do?
Atoms undergo thermal vibrational motion while held in a lattice by covalent ionic metallic or other forces which hold them together but at the same time the thermal energy present at room temperature they vibrate on their lattice site itself
What happens to an ideal gas in a closed container when temperature rises?
In a container of constant volume, when the gas is heated, thermal energy is converted to kinetic energy. This increase in kinetic energy causes the gas particles to accelerate. This acceleration of particles causes the particles to crash into each other, increasing pressure. Because it is a closed container, the number of particles and the volume the particles take up remain the same.
What is heat transfer through conduction?
Conduction refers to heat transfer through solids. It is due to conduction that if we heat one side of a rod and place our hand on the other side, we feel the heat.What, basically, happens is that at the point that you have heated the rod, the particles gain more energy. As the particles in a solid are fixed in their position - and can only vibrate - due to the increase in eneery, the particles vibrate faster about their equilibrium positions. When they vibrate faster, they cause the particles around them to also vibrate faster, increasing their temperature. When these particles also start vibrating faster, the cycle is repeated and they cause the particles around them to also vibrate faster, increasing their temperature as well. In this way, the disturbance is spread all over the rod, which is why you feel the heat on the other side of the rod, even though that side is not in direct contact with the heat.
When you boil water what do the particles do?
The particles gain energy (kinetic energy) and begin to vibrate. This vibration causes heat. As the particle vibrates, it will collide with other particles in water and pass this energy on to neighbouring particles which causes the heat conduction.
How does heat affect particles?
heat affects particles by making them move about faster and vibrate more passing more energy to other particles.
How does air pressure change when put in heat?
When energy is added to anything, the particles of the substance vibrate faster. In the case of air, the particles increased motion causes them to hit the walls of the container and each other more often and with greater force. This causes increased pressure.
Why is it became colder when you release energy?
Releasing energy means particles do not vibrate as much as previously. They therefore draw on the energy from other nearby particles, who then draw from others, and so on. Eventually there is a decrease in the total vibration and therefore collective energy of all particles. Less energy equals less heat.
How are the paricles in a liquid?
Particles in a liquid have only a small amount of space between each other. They have more energy then solid particles but less energy than gas particles. Particles in liquid roll over each other this is what causes water to flow.

What happens to the sound when you speak?
When you speak, your voice box vibrates. These vibrations cause the surrounding air particles to vibrate as well. These air particles in turn cause the other particles to vibrate. Energy is carried off in this manner into your ear. When the vibrations reach your ear, the receptor cells in your ear-drum send electrical signals to your brain, which interpret it as sound.

Particles in a liquid move around just as freely as particles in a solid?
Solid: Locked in a crystaline structure, however they do vibrate slightly. Liquid: Particles are attracted to one another but can flow freely. Gas: Particles move with total freedom.
In which state of matter do particles vibrate in place?
The solid state of matter is the phase in which particles vibrate in space. Because particles in a solid are so tightly packed together, they can vibrate but not move to any significant extent. However, in liquids and gases, the molecules are free to vibrate was well as move around.
