All get very hot.
A substance in the solid phase will typically expand when heated. Most substances when heated sufficiently will melt into a liquid, assuming that they do not combust or sublimate.
Most substances expand when heated.
electrons spontaneously "jump" from a lower orbital to a higher one
When heated, most substances expand due to the increase in kinetic energy of their atoms or molecules. This leads to an increase in the average distance between the particles, causing the substance to expand.
expand
When substances are heated, typically their molecules gain energy and begin to move more rapidly. This increased movement can cause the substance to expand, change phase (from solid to liquid or gas), or even chemically react to form new substances. The specific changes depend on the substance's properties.
Most substances expand as they are heated because the increase in temperature causes the individual particles to move faster and spread out, resulting in an overall increase in volume. This expansion is due to the increased kinetic energy of the particles.
The process is call decomposition.
It expands
Generally, the density of solids, liquids, and gases decreases as they are heated. When heated, the particles in these substances gain energy and move more, causing the substance to expand, which leads to a decrease in density.
materials usually expand when heated.
When substances are heated, their molecules gain energy and move more rapidly. This increase in molecular motion can cause substances to change state (e.g. from solid to liquid), react with other substances, or decompose into simpler chemical components. Ultimately, heating a substance can lead to a variety of physical and chemical changes depending on the specific properties of the substance.
