The velocity of the atoms/molecules (that the substance is made of) increase.
When a substance is heated, it gains thermal energy. This increased energy causes the substance's particles to move faster and its temperature to rise.
Thermal Decomposition
When something is heated, the temperature of the substance increases, causing the molecules in the substance to move faster. This increased molecular movement can lead to changes in the physical state of the substance, such as melting or boiling.
The substance formed when iron is heated in the presence of oxygen is called iron oxide, commonly known as rust.
When a substance is heated, it may undergo physical or chemical changes such as melting, evaporation, sublimation, or decomposition. These changes can result in alterations in the substance's physical state, color, texture, or chemical composition.
They increase in energy.
Any substance that absorbs the radiation is heated by it.
When a substance is heated, the particles gain energy and vibrate faster, causing the substance to expand. As the temperature increases further, the particles can reach a point where they break free from their fixed positions and transition from a solid to a liquid state.
its heated with something
They expand
The substance may oxidize or undergo combustion in the presence of air, depending on its properties. If heated, the substance may decompose, vaporize, or react with air to release gases. It could also undergo thermal degradation or combustion, leading to potential hazards like fire or explosions.
The volume of a substance increases when heated

The substance created when zinc is heated with sulphur is zinc sulfide.
When a substance is heated, it gains thermal energy. This increased energy causes the substance's particles to move faster and its temperature to rise.
