They expand due to the molecules speeding up.
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.
Most substances expand and become less dense when heated because the increased thermal energy causes the molecules to move farther apart, which decreases the density. However, there are exceptions such as water, which becomes denser when heated from 0°C to 4°C due to its unique behavior when transitioning from a liquid to a solid.
When nickel is heated, it undergoes a color change from silver to a pale yellow color. It also becomes more ductile and malleable, allowing it to be shaped easily. Additionally, heating nickel can increase its reactivity with certain substances.
Most materials expand when heated due to increased molecular motion, causing the particles to move farther apart. However, if heated to extremely high temperatures, materials can undergo phase changes, such as melting or vaporization. Additionally, some materials may decompose or undergo chemical reactions when heated.
Materials such as glass and ceramics do not decompose when heated because they are not organic compounds and do not break down into simpler substances under high temperature.
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
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.

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.
