How would I create a block with gas physics.

What have you tried?

What have you tried so far? And what exactly do you mean by a block having "gas physics"? Like it would spread out if it has space?

I have tried using a radius instead of a block but that didn't give me a desired effect. Yes, I mean it would spread out if it has space

You have no idea what you're doing, do you?

Not really.

Write your idea down.

Go back to the basics.

Step 0: learn Java

Step 1: make some basic blocks that look pretty

Let me elaborate on radius. If the player is within the radius he/she will experience desired effect. I noticed that this does not allow for air pressure and other things.

Edit: I ment to post this before you posted that.

Okay, so you want a block that is a source of a gas that spreads an effect and spreads out further over time?

 

In that case you would make a gas source block that has a tile entity. The tile entity could search the surrounding area over time and put an effect on any entities it finds, with the range growing. 

 

Look up tutorials on making tile entities. Try to make one, then post your code if you need more help.
