A metal cylinder in Physics can serve various functions depending on the context. It can be used as a conductor in electrical circuits, as a magnetic material in electromagnets, as a container for gas pressure experiments, or as a component in mechanical systems like pistons or bearings.
A metal cylinder is a three-dimensional shape with circular bases at each end and straight sides. It is typically hollow and used for storing liquids or gases, such as in the case of a canister or a metal water bottle.
Metal cylinders are commonly used for containing gases under pressure, such as in compressed gas cylinders for welding or in gas storage tanks for various industrial processes. They are also used in hydraulic systems, for storing liquids in hydraulic machinery. Additionally, metal cylinders are used in automotive applications, such as in engine cylinders for combustion.
LPG / propane expands when it turns from liquid to gas, and this process absorbs heat energy from the air, via the cylinder. This causes cooling and often condensation of water vapor on the tank.
No, paper will not keep water cold for the longest time. A metal cup will keep water the same temperature for the longest time. I know this because I did a science experiment about this but instead of cold water I used hot, which won't really make a difference. The next would be glass then paper.

"the Cold saw, used for cutting metal, transfers the heat into the chips dispersed by the machine, keeping the metal and sawblade cool." "A cold saw used to be much harder to operate, but now it's farily simple. It works much like any circular saw."
Cold rolling produces a better finish and is generally used for automotive body panel sheet metal. See link
It could sink. (The metal's density is greater than water.) It could turn into a ball of flames. (If you dropped a chunk of sodium into graduated cylinder, it would react with flames or sparks.)
The materials vary, but some of the better gaskets are composed of kevlar and metal.

A fusible plug is a metal cylinder that has been threaded with a hole drilled throughout it. The plugs can be found in a variety of metals. Heated metal is used to seal the hole.
Metal is a good conductor of heat, so it can help keep things cold by transferring heat away. Copper is even better at conducting heat than most metals, so it is also good at keeping things cold. Both metal and copper can be effective materials for keeping things cold when used in coolers or refrigeration systems.
