Finding answers for homework questions can sometimes be challenging, but there are a few strategies you can use to find the information you need. Here's how you can approach finding answers to your questions:

1. Utilize search engines: Start by searching for each individual question on popular search engines such as Google or Bing. Enter the question in a clear and concise manner, like "Why is wool warmer than silk?" or "Why is silk stronger than wool?" This will help narrow down your search results to relevant sources.

2. Check reliable websites: Look for reputable sources such as educational websites, scientific articles, or publications related to textiles and fabrics. Websites ending in .edu, .gov, or .org are generally considered more reliable sources. For example, you could search for articles from textile industry experts or scientific studies comparing different fabric properties.

3. Use keywords: When conducting your search, try including specific keywords related to the topic. For instance, use words like "insulation properties" or "fabric strength" in combination with "wool" and "silk" to find information directly addressing these qualities.

4. Research comparative studies: Look for comparative studies or research papers that directly compare wool and silk in terms of their warmth, strength, and price. These studies often provide in-depth explanations and scientific evidence to support their findings.

5. Consult textbooks or reference materials: If you have access to relevant textbooks or reference materials on fabrics or textiles, they can provide valuable information and explanations. Check the index or table of contents to locate relevant sections within the book that discuss wool and silk properties.

Remember, it's essential to cite your sources when using information from external references or online sources. This ensures you give credit to the original authors or researchers and maintain academic integrity.

As for the answers to your specific questions:

1. Why is wool warmer than silk?
Wool is warmer than silk because of its natural crimp or waviness, which creates air pockets and traps warm air close to the body. This insulation property helps retain heat and keep the wearer warm in cold conditions.

2. Why is silk stronger than wool?
Silk is stronger than wool due to its unique molecular structure. Silk fibers have triangular-shaped proteins called fibroin, which create strong bonds. These bonds make silk more resistant to tearing or breaking compared to wool, which is made of different proteins called keratin that have a different structure.

3. Why is silk more expensive than wool?
Silk is more expensive than wool mainly because of the labor-intensive process involved in its production. Silk is produced from the cocoons of silkworms through a process called sericulture, which requires manual extraction of silk threads. Additionally, silk also requires more resources and time to produce compared to wool, which contributes to its higher cost in the market.

Remember to validate the information you find using multiple sources and critically evaluate the credibility of the information before using it for your homework. Good luck with your research!
