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
Given that the gas or liquid cannot pass through the block (and I hope this is a consensus opinion), there is a very long and complex chain of events to get it through. I'm starting at the top of the liquid and working my way down, hoping to find out what is the final answer.

1. Pressure difference across block
- if gas or liquid pressure on one side is greater than the other, the gas/liquid won't go
