Wood expands primarily across its width, perpendicular to the grain, when exposed to moisture or changes in temperature.
No wood does not expand when its dry
Wood would expand about 0.3 millimeters if heated to 100 degrees
To determine the direction of the wood grain for sanding, run your hand over the surface of the wood. The direction that feels smoothest is the direction of the grain. Sand in the same direction as the grain to avoid damaging the wood.
Yes, wood does expand when it gets wet due to the absorption of water into its fibers, causing them to swell.
Yes, wood expands when exposed to heat.

It is not a good practice, but people do it. Some will tap a screw with a hammer to start a hole. Others will drive it all the way in. That is bad for the screw and the wood.Hammering a screw is counter-productive and will not have good results:When you hammer a nail into wood, the sides of the nail compress the wood. The compressed wood wants to expand pressing on the sides of the nail. The pressure keeps the nail in place preventing it from coming out of the wood.When you hammer a screw into wood, the threads of the screw "chew out" the wood pressing it downward, possibly compressing it in a downward direction, leaving little or no wood to hold the screw in place The compressed wood, wanting to expand may tend to expand upwards pushing the screw out.
The direction that fibers run in wood is called the grain. Grain direction is important in woodworking as it affects the strength, stability, and appearance of the wood.
Material such as wood allow the concrete to expand
Wood expands and contracts in response to changes in temperature and humidity.
When wood is heated, the molecules within it gain energy and move more, causing the wood to expand. This expansion can lead to changes in the structure and properties of the wood, such as warping, cracking, or weakening of the material.
Yes, especially if it gets damp!
