Let's say that we have a gaseous or liquidus compound (I don't know if elements or compounds make a difference, take this as a thought experiment), and we have a tungsten or steel block that's 5cm (or less, you choose) thick. Is there any physical method for that gas or liquid to pass through that thick heavy metal block (not by drilling etc.)?
Physically yes, but it would take a very long time because a gas or liquid would have to apply an immense amount of pressure to get through that thick of a metal. If we take water for example, the pressure required to force water through a 5 cm thick steel block at room temperature is approximately 5.5 gigapascals.

It's important to note that gases and liquids are not able to pass through solid materials like a steel or tung
If my question itself may be unclear, I can provide more specifications or examples if need be. My intention is to find out how deep a gas, or even just a tiny drop of some sort of liquid can penetrate through a heavy solid metal block, and why.

I'm just thinking of a scenario where a gas or a drop lands on the surface of a large thick metal shield. I know that's not a question that can be answered definitively just by
