When particles are heated, they gain energy and move more vigorously. This increase in kinetic energy causes them to vibrate or move more rapidly compared to their state at lower temperatures. Therefore, heated particles move more, not less.
When a solid is heated its particles melts and change into liquid
No, particles actually vibrate faster when they are heated. This increase in vibration is due to the higher energy levels associated with the increase in temperature.
Ninhydrin is used as a visualization reagent in thin layer chromatography to detect amino acids and other compounds that contain primary amines. When sprayed onto the developed TLC plate and heated, ninhydrin reacts with primary amines to form colored products, allowing for visualization and identification of the separated compounds.
When a metal bar is heated....the particles in the area of the metal bar that is hot start vibrating.. knocking into each other and passing the heat energy on to cooler particles. The cooler end that isn't heated still has a rise in temperature just not as much as the heated area because the heat has almost been diluted.

In heated compounds, electrons are the particles responsible for the production of colored light. When the compounds absorb energy and become excited, electrons jump to higher energy levels and then release the excess energy as photons of light when they return to their original energy levels. The wavelength of the emitted light determines the color observed.
Yes, nitrate compounds can produce colored flames when they are heated. These compounds are often used in fireworks and pyrotechnics to create vibrant colors in the flames.
The particles in a liguid are bonded (not as strongly as a solid which is why it flows.) when it is heated the particles vibrate and eventually the bonds break and the particles break away. This is evaporation.
When particles are heated or cooled, they do not change size at all. They simply move with greater kinetic energy so the space between particles increases. This prompts the changes in size we see when substances are heated or cooled.
The speed of the gas particles will increase as they are heated. That is why the pressure in a container increases. The particles are hitting the walls of the container with more force as they are heated.
the answer is particles !
accelerate
When a solid, liquid or gas is heated the particles in the substance speed up and gets less dense. The particles also spreads out.
