water, it freezes when it is cold and turns to steam when it is hot.
Brass is the combination of the metals copper and zinc. Its manufacturing process involves melting, hot rolling, annealing and cold rolling, and finish rolling.
When iron is smelted from its ore by commercial processes, it contains more carbon than is desirable. To become steel, it must be melted and reprocessed to reduce the carbon to the correct amount, at which point other elements can be added. This liquid is then continuously cast into long slabs or cast into ingots. 96% of steel is continuously cast, while only 4000 ingots are cast per year. The ingots are then heated in a soaking pit and hot rolled into slabs, blooms, or billets. Slabs are hot or cold rolled into sheet metal or plates. Billets are hot or cold rolled into bars, rods, and wire. Blooms are hot or cold rolled into structural steel, such as I-beams and rails. In modern foundries these processes often occur in one assembly line, with ore coming in and finished steel coming out. Sometimes after a steels final rolling it is heat treated for strength, however this is relatively rare. Hope this helped
I have found through experience that hot rolled steel will take 95/5% solder, and that cold rolled will not solder, reason is the cold rolled steel molecules are arranged differently that the hot roll, they are so to speak pushed into the final dimension with extreme pressure this also causes a so called hardened tempered surface on the cold roll steel that has to be annealed so that it can be drilled. cut or soldered.
You need to define "metal"- since different metals have VERY different melting points. Mercury is melted at room temp. Gallium can melt in boiling water. Lead and tin are mixed as solder, and melt at fairly low temps. Gold and silver melt at moderate low temps. Aluminum is higher. Steels and hi temperature tungsten alloys will glow white hot before melting. So- which metal did you have in mind
EOT means Electrically operated travelling Crane and HOT means Hoist (One Track) crane
Water expands when it freezes and becomes ice.
When something gets hot it expands and when it gets cold it'll contract
freezing, very cold, cold, lukewarm, warm, hot, very hot, boiling
Cold air is more dense than hot air. This is because gas expands when it is heated.
Mercury is put in a tube the Mercury expands when it is hot and compacts when cold.
FIRE for HOT andICE for COLD
very,very hot/cold
The words hot & cold are relative.90 c = 194 f.For humans, that temperature is very, very hot.Too hot for us to live.
it is very hot
A desert is a dry environment; it is very hot in the day and very cold at night
Cold. Very cold.
very cold
