How can you tell between ground state and excited state? what is the difference between ground state and excited state class 11.
You can use a moisture tester to gauge whether your firewood is ready to burn but there are a few other ways to check. Well-seasoned wood always looks darker than green wood of the same species. Unseasoned wood has a fresh bright color, while seasoned wood looks yellowish or greyish in comparison.
Use leaves and bark for identifiers. Split wood may not have leaves, but often branches or twigs will have remnants of leaves that can identify firewood. Pines, cedars, firs and other softwoods have needles rather than leaves, which is a good identifier. Check the bark; there should be some on at least some logs.
To identify well-seasoned wood, you just need to look at the ends of the logs. If they are splitting and dark in colour like the log on the right, they are dry. Dry wood is also much lighter in weight than wet wood, and makes a distinct hollow sound when two pieces are hit together.
One precaution includes removing the bark from the firewood. Bark has creosote, which can build up in the chimney and cause a chimney fire. Removing bark will also help you avoid insect infestations in firewood.
Hardwood logs come from sturdy, slow-growing trees such as oak, birch and ash that shed their leaves during the cold winters and deliver a variety of strong and thick firewood. Softwood logs come from evergreen trees that tend to grow faster, such as Larch, Douglas fir and Spruce.
Seasoned wood will be darker in color than green wood, and may be cracking at the ends. Seasoned wood can also lighter in weight and the bark can be peeled off more easily than unseasoned wood. A moisture meter will be able to provide an accurate reading of whether firewood is fully seasoned or not.
Hardwoods have either simple or compound leaves. Simple leaves can be further divided into lobed and unlobed. Unlobed leaves may have a smooth edge (such as a magnolia) or a serrated edge (such as an elm). The most common North American tree is the red alder.
You can recognize hickory by its medium-brown, reddish hue, with yellow or gold highlights. Depending on the wood’s grade, hickory may display black streaks or knots.

To identify oak trees, look for bark that has deep fissures and ridges, giving it a scaly look. The bark color of oaks ranges from whitish-gray to dark, almost black. You can identify oak trees by their deeply lobed leaves with pointed or rounded tips.
Not long burning & low in BTUs but nothing wrong with burning it. Dry bark shouldn’t create any more creosote than dry wood. Creosote comes from burning unseasoned wood slow & at low temperatures.
Bark-on wood has been known to cause more flare-ups than skinned wood, owing to the volatile texture of the bark itself. This is potentially harmful to the finished product, as smoked food is at its best when the temperature remains consistent throughout the long process.
Usually, hardwoods are regarded as better firewood. Because they are dense, they burn longer and produce more heat than softwoods. … You’ll get a more even cook from hardwood coals than from softwood flames. Some good hardwood choices are oak, birch, ash, cherry, apple, and maple.
A lot cheaper than hardwood, softwood can also be used in your wood burning stove. Fir is the most popular choice, although there are plenty of other options, including balsam, pine, spruce, cedar, alder, tamarack and poplar.
Hardwood logs are best used to keep a fire going. Hardwood logs can burn for up to five hours – so you can sit back, relax and enjoy. Hardwood logs are much more dense than softwood logs. If you dare to attempt to light a fire with hardwood logs, even kiln dried ones, it really would be like trying to light a brick!
No matter which way you cut it (or split it with your trusty log splitter), fresh wood just doesn’t burn right. Fresh-cut wood has a high moisture content, which makes it hard to get burning. It also gives off more smoke.
Since your trees are already dead, the curing process will have already started, and the wood should be dry enough to burn in a shorter time period. … The best wood is typically seasoned for two to three years but will start to deteriorate after four to five years and will not be good to burn.
Finally, unseasoned wood does not create nearly as much heat when burned as seasoned wood. … Conversely, the seasoned wood has little or no water to waste the energy of the fire, so it burns very hot. Fast lighting, sustained burning, clean burning, and more heat are the basic benefits of burning seasoned wood.
LeafSnap allows you to identify a plant by leaf, flower, fruit, or bark.
- Leaf type, shape, appearance, texture and colour are all key characteristics when identifying trees.
- They are also often the most obvious feature, particularly in spring and summer. …
- The leaves of broadleaved trees fall into two basic types – simple and compound.
Leafsnap is a free app that identifies trees. Go for a walk, take a shot of a leaf and this little wonder will identify its tree and give all kinds of information about it. The app is a result of a collaboration between Columbia University, the University of Maryland and the Smithsonian Institution.
The best way to identify hickory trees is by their bark, leaves, and nuts. Hickory leaves are long with up to 17 pointed leaflets growing oppositely on each leaf stem. Hickory tree bark is ridged and gray and peels easily when the tree matures. Nuts from the common hickory trees are sweet.
Color/Appearance: Heartwood tends to be light to medium brown, with a reddish hue; sapwood is a paler yellowish brown. Boards with contrasting heartwood and sapwood create a somewhat rustic appearance that’s sometimes marketed as Calico Hickory.
Start by taking a small sample from your load and holding a flame to it. When you do so, you will find that hickory has a strong aroma that hits you like a train the second the smoke goes into the air. Oak, on the other hand, is a lot more subtle.
Buds can be helpful in identifying tree species in winter, when deciduous trees are without foliage. Those at the end of a twig are called terminal buds, while those growing along the twig are lateral buds. The arrangement of these lateral buds can help establish a tree’s identity.
You can use Google Lens to identify real-world objects with your camera and find information about plants, animals, landmarks, restaurants, products, and more.
What Color is Maple Wood? Whereas many trees are prized by woodworkers for their heartwood, it’s usually the sapwood of maple that’s used in fine wood furniture. It tends to be a white hue with pitch fleck and mineral streaks adding some reddish-brown tints to it, though the color will deepen some with age.
African Blackwood It is considered as the most expensive wood in the world because not only it is challenging to work with hand or machine tools, its trees are already near-threatened. But as expensive as it may seem, African Blackwood is worth the price.
Walnut is a strong, yet lightweight wood. It has a gorgeous chocolate brown coloring, with a usual straight grain. It’s also known for its burl wood pieces, with distinctive figured grain and dark streaks. Wood closer to the roots has more of a wavy grain than the straight-grained trunk.
Cherry has a simple, fine, closed grain, much like that of maple. You can see the grain pattern pretty well in the Cherry Moon bed above. Fake “cherry” wood often has little or no grain pattern. It’s made by taking a cheaper wood, bleaching it, texturizing it with chemicals, then staining it with a “cherry” stain.
Typing a bunch of words into Google’s search box doesn’t necessarily bring you specific results, even though the database is vast. … But Google Lens can identify the plant as Pacific poison oak in seconds.
Watch out for any wood covered with vines. Burning poison ivy, poison sumac, poison oak, or pretty much anything else with “poison” in the name releases the irritant oil urushiol into the smoke. Breathing it in can cause lung irritation and severe allergic respiratory problems, the Centers for Disease Control state.
Burning Hunk i hear of a lot of people using it as kindling, but every time i throw random bark in to start a fire (stove or fire pit) it smokes a lot more than my liking. if the fire is already going well, or it’s attached to the wood it doesn’t seem to though.
As for the bark, if we use it, then it goes into low spots in some of the trails in the woods. You can burn the bark if you like but you get lots of smoke and ashes for a little bit of heat. On the other hand, those tiny pieces you get, let them dry before you bad them and then you can use them as kindling wood.
