If the wooden block floats on the water surface, add salt into the water and stir it evenly. After the module is still, the pressure on the bottom of the cup will be (the buoyancy on the wooden block will be ((select "increase", "unchanged" or "decrease") and explain the reason (more details), Some people say that the depth will not change after adding salt, but I think the depth should decrease. Second, I understand,

I'm dizzy. Let me add
1. Increase
We can't use p = pGH, because the liquid depth changes! Let's study it by ourselves... The wood block will rise, and the liquid level will drop. But overall, the total g will increase, and the bottom area will not change, so the pressure will increase
2. Unchanged
Floating, buoyancy is equal to gravity, and the gravity of the wood block does not change, so the buoyancy does not change!
