The minimum amount of material needed to sustain a nuclear reaction depends on the type of reaction. For example, in a nuclear fission reaction, a critical mass of fissile material is needed to sustain a chain reaction. In a fusion reaction, high temperatures and pressures are needed to overcome the electrostatic repulsion between nuclei.
When distortion occurs in a dental material, it typically undergoes a physical or chemical reaction. Physical reactions involve changes in shape or size due to external forces, while chemical reactions involve bond breakage or formation due to exposure to certain substances or conditions. It's important to identify the type of reaction to determine appropriate corrective measures.
An electrical spark is not. It is merely electrons flowing and that may cause a reaction. A fire type spark, is not either, but the fire is. A 'spark' that is a slmall ember of burning substance that 'jumps' from a fire is a burning material, so there is a chemical reaction of burning, also called oxidation, going on.
Acids can corrode certain materials through a chemical reaction that breaks down the structure of the material. When an acid reacts with a material, it can dissolve or eat away at the material's molecules, leading to corrosion or degradation of the material. The strength and type of acid, as well as the type of material being exposed to the acid, will determine the extent of the damage.
The type of reaction that involves oxygen and produces light and heat is a combustion reaction.
