hey im doing my science homework and i really need hel fast cuz i need a discription(definition), a sentence, and a pic. for thermal expansion, exfoliation, dissolution, oxidation, and hydrolysis i would look in my text book but none of those words are in there i know because my teacher told me and i looked so can somebody please help QUICK.:) =)THANKS EVERY BODY SO MUCH
If you Google each of these terms, you'll find a wealth of information from which to choose.

Of course, I can help you find the description, a sentence, and a picture for the terms you mentioned: thermal expansion, exfoliation, dissolution, oxidation, and hydrolysis. Let's go through the process step-by-step:
1. Thermal Expansion:
- Description: Thermal expansion refers to the tendency of matter to change its shape, volume, or dimensions in response to a change in temperature.
- Sentence: "Thermal expansion is the reason why the metal of a bridge expands on a hot summer day, causing it to slightly curve upwards."
- Picture: You can search for "thermal expansion" on a search engine (e.g., Google) and go to the "Images" tab to find a visual representation of thermal expansion.
2. Exfoliation:
- Description: Exfoliation is the process of peeling or flaking off thin layers from a surface, typically in the form of sheets or scales.
- Sentence: "The exfoliation of rocks occurs when layers of rock peel away due to weathering and erosion, resulting in a unique geological formation."
- Picture: Again, search for "exfoliation" in an image search engine to find visuals related to this process.
3. Dissolution:
- Description: Dissolution is the process of a substance being dissolved in a solvent, resulting in a homogeneous mixture at the molecular or ionic level.
- Sentence: "When table salt is added to water, it undergoes dissolution, where the salt crystals break down and disperse throughout the liquid."
- Picture: Look for "dissolution" on an image search engine to find appropriate visuals.
4. Oxidation:
- Description: Oxidation is a chemical reaction that involves the addition of oxygen or the loss of electrons by a substance.
- Sentence: "When iron reacts with oxygen in the air, it undergoes oxidation, resulting in the formation of rust."
- Picture: Search for "oxidation" to find visuals representing this process.
5. Hydrolysis:
- Description: Hydrolysis is a chemical reaction where water molecules split a compound into two or more products.
- Sentence: "During the process of hydrolysis, large polysaccharide molecules are broken down into individual sugar units by the addition of water molecules."
- Picture: Perform an image search for "hydrolysis" to find relevant pictures.
