I'm working on a 2D minecraft-like game, I use chunks to save my world and each chunk has 128*128 blocks in it.
And infinite chunks can create an infinite world.

Memory should never be infinite and only several chunks near the character shown in the screen can be loaded into memory. How can I handle logic based blocks like red stone signals when they are in chunks far away and so not loaded in memory?


Question: Why Ionic compounds dissolve into water
Answer: An individual IMF bond is weaker than an ionic bond. But when a salt dissolves, at least 4 IMF bonds are formed for each ionic bond. This is why some salts (e.g. CaCl2) release heat when they dissolve.
