Normally stainless steel. But cast iron coated with enamal and galvanized steel were also used.
yes metal sink in water
That depends what it's made of ! A metal one will sink, but a wooden or plastic one will float.
ummm boats can't be made out of medal, they just sink if it is.
Weights are usually made of metal, which is denser than sea-water, so they would sink. But, to be awkward, if it were made of wood, it would not sink.
It all depends on what it is made of. Some made of metal will sink and others made of wood will not. Also the amount of air inside the enclosed part will also determine if it will or will not float.
It depends what the sink's made of. Neat bleach should remove the stains but if it's a metal sink then that could cause rust. If it is metal or enamel sink then try scrubbing it with biological washing powder and salt - and make sure you rinse it very well after.
Canoes do sink. Metal canoes will sink if they are turned sideways and loose their air pocket. Wood canoes normally do not sink if they are not waterlogged as the wood is buoyant. The same can be said for canoes made of other buoyant materials.
The anchor is a solid lump of metal so it sinks, but a boat is hollowed out so that even if it's made of metal it still has buoyancy.
Yes, gold is a heavy metal and will sink in water.
Paperclips sink in water because they have a higher density. Unlike wood, a paperclip will sink not float.
Because - the purpose of a heatsink - is to expel heat from the computer... plastic is an insulator - not a conductor !
no it's because it hit an iceberg not because of the metal
