The simple act of drying a leaf (removing water) would not be a chemical change, but would represent a physical change. This is because if you were to re-hydrate the leaf, you should, in theory be able to make it the same as it was. However, the consequences of drying a leaf, i.e. what happens to various components of the leaf when water is removed, would represent a chemical change.
The answer is D ! (a) melting ice to obtain water - is changing waterfrom its solid form to liquid by heat. (b) evaporating alcohol into vapour - is changing alcohol from liquid to a gas. (c) drying wood in a shed - is simply allowing Amy moisture present in the wood to evaporate. In all three of these cases the original material remains chemically unchanged. in (d) burning coal in a furnace - the cellular structure of the wood is broken down by heat - the individual wood cells are destroyed, turning it from cellulose to carbon.
Lint is typically made of tiny fibers that shed from clothing, towels, or bedding during the washing and drying process. It is composed of a combination of natural fibers like cotton or wool as well as synthetic fibers like polyester or rayon.
A benefit of a plastic garden shed over a wooden garden shed is that the plastic shed will not rot, as it is not biodegradable, therefore will not break down as quickly as a wooden garden shed would.
The biggest plastic shed you can buy at Home Depot is 15 ft. x 8 ft selling for $1,699.99. The also sell a wooden one that is 16 ft. x 12 ft for $2,795.00 and a metal one for 10 ft. x 14 ft. for $499.00.
Plastic storage sheds can be purchased at home improvement stores like Home Depot or Lowe's, online retailers such as Amazon and Wayfair, or directly from the manufacturer's website. It's important to consider the size, quality, and features of the shed before making a purchase.

A king cobra keeps from drying out by shedding its skin. King cobra shed their skins 4-6 times per year for adults, and every month for juveniles.
no
They shed one and grow another

Lumber must be seasoned to prevent it from cracking and warping. After being cut into boards, the lumber is dried (seasoned) in a heated drying shed called a kiln or in the open air.
Ummm I'm pretty sure it must shed it's skin because they don't have fur coats
They shed often but it you brush them in the morning they shoUldnt shed in the day time
No. Koalas do not shed, nor moult nor change form in any way with the changing seasons.
A result of a seasonal change is the transformation of deciduous trees, which shed their leaves in autumn and regrow them in spring. This cyclical process helps trees conserve water and energy during the colder months. Additionally, seasonal changes influence animal behaviors, such as migration patterns in birds and hibernation in certain mammals, as they adapt to varying temperatures and food availability throughout the year.
