I need ideas of how to make an ice cube melt fast WITHOUT touching it AND how to make it last longer also WITHOUT touching it.For class we have to get into groups and do both experimentsWe have racked our brains and are looking for guidance.Any ideas??
You didn't state the wall thickness of the steel pipe or but a sch 40 steel pipe seamless or erw will hold 1000 psi with no trouble As to threaded end caps, I'm not sure you can find such animals in the real world for 8 inch pipeIf you were to close the ends of the 8 inch pipe with welded pipe caps or blind flanges of the correct pressure rating then there would be no problem with the pipe holding 1000 psi A simple flat plate would not hold that much pressure.
The walls of the tank are thicker, and the valve, along with the opening where the valve is located, is stronger then a pipe jointThe tank is probably also made of a stronger material.
if you notice cylinders are roundCompletely, on the top and bottomIt is by using this cylindrical shape and also the density of the steel that makes it capable of withstanding such pressure.
You could blow warm air on it to melt ityou could shine a light on it to melt itTo stop it from melting, try putting an inverted styrofoam cup over it as insulationTry tenting aluminum foil over it to reflect any light rays.
