The glass tube is filled with mercury gas. Electricity causes the gas molecules to vibrate faster. The increased motion excites phosphorous in the tube and causes it to give off visible light.
Loss of electrons causes NADH to become NAD+. This cycle of oxidation reduction helps generate ATP in cell respiration.
An increase in thermal energy gives particles more kinetic energy, which causes them to vibrate more. As they vibrate more, the volume they take up increases.For example, when ice water is heated up, the molecules spread out, take up a greater space, and so the result is liquid H2O.The reverse scenario - when gaseous water ('steam') is cooled, due to a reduced level of thermal energy - is that the particles will vibrate less and the substance will contract. The steam will condense into liquid water.
hot water contains more energy than cold water. cold water causes the water molegules to vibrate more.
i believe heat does expand... I'm not sure though. i think the particles separate to have room to vibrate. that causes the heat to expand. :)

When particles receive energy (like heat) usually it causes the particle to vibrate. If this particle is next to another particle, the vibration causes the particle next to it to vibrate. This vibration is the heat energy being given off, and colliding with the next particle, which then collides with the next particle, then the next, etc.This is the case with solid and liquid particles, however gas particles use convection, which is where the gas particle hits another particle, and so transfers some of the energy (such as heat) to that particle.Conduction ConvectionA;vibrate;B;vibrate:C A->->->;collide;B->->;collide;C

a loud clap of thunder causes a window to vibrate
Playing the instrument cause the strings to vibrate. This vibration is then transferred to the air, and vibrations in air is basically what makes up a sound.
A saxophone reed is used to put on the mouthpiece and when you blow onto the mouthpiece it causes the reed to vibrate and generate sounds. This is how the sounds are made in a saxophone.

When an object vibrates, it forces the neighbouring particles of the medium to vibrate. These vibrating particles then force the particles adjacent to them to vibrate. In this way, vibrations produced by an object are transferred from one particle to another till it reaches the ear.
it cause it to vibrate!
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.
Heat!
