If slate is sufficiently heated and compressed it becomes phyllite.
Heat information is conducted through neurones. Higher frequency action potentials are perceived in the brain as a hotter stimulus. So the heated rod would have sent higher-frequency action potentials than the cool rod would have.
hydrate
Barium Chloride becomes a yellow/green when heated
When it is heated, it becomes very brittle....And it is very hard to work.
when glass rod is heated ,it melts. Now a liquid having surface tension ,tends to have least surface area.we know that a spherical surface has least surface area compared to other shapes of same volume.so end of a glass rod becomes round when heated .........geddit :)
When heated, steel becomes malleable, and can be hammered into shapes.
One common method was known as Twist Steel. Thin steel rods were heated, and twisted together. They were reheated, and twisted around a metal rod. While on the rod they were heated a 3rd time, and hammered to weld the twisted strips together. After cooling, the rod was removed, leaving a hollow tube. One end would be fitted with a plug, the other left open to load powder and shot.
It becomes harder and tougher. Manganese steel is what soldiers helmets were made out of in WW II.
The weight of 1 foot of steel rod would depend on the diameter of the rod.
Yep, you can weld steel to stainless and you can weld stainless to steel. You can use steel or stainless welding rod in either case but the steel or steel welding rod will of course rust.
Heat the plate then, insert the rod. Hole in plate slightly smaller than rod.
After reaching thermal equilibrium stage the heated rod attains the same temperature at every point.
Hollow section steel rod rust when in contact with water.
Yes, you can weld steel to steel. You can use steel welding rod.
The steel would EXPAND
