A submarine sinks as it fills its' ballast tanks with water. Then it uses pressurized air to empty them and float again.
this is like warm, less dense air rises while cool more dense sinks. This is like the lava lamp the hot "lava" floats up to the top and and the cooler "lava" sinks down to the bottom and heats up and rises and the cooling stuff at the top is now sinking
A submarine is a ship that sinks itself in a controlled manner by flooding tanks with water and returns to the surface in a controlled manner by blowing the water out of those tanks with compressed air. The main uses of submarines so far have been military, where a ship that cannot be seen is needed.
He is a submariner.
A hydrometer works by measuring the density of a liquid, which is related to its specific gravity. The hydrometer floats in the liquid, and the depth at which it sinks indicates the density of the liquid. By comparing this to the density of water, the specific gravity of the liquid can be determined.
work in basically the same as a convented submarine
ummmm i think its a sailor!
You go up. This is how a balloon works. As you go higher, the air gets thinner and the upthrust gets smaller. Eventually you don't go any higher.
A lava lamp is a pretty interesting thing, when it is cool, it looks like it's made of candle wax, because it is. Wax is strange, because when it is hot, it rises, but when it is cool, it sinks, so the bulb at the bottom heats the wax, and it floats to the top, but at the top, when it starts to cool down, it sinks. cool huh?
You keep attacking its tentacles (Silver Sword, strong style) until it raises its head above the water. Do as much damage to the head as you can, before it sinks down again and you have to defend yourself from the tentacles again. Igni works well on the head.
Lactometer is a device used for finding the purity of a milk sample. It works on the principle of Archimede's principle that a solid suspended in a fluid will be buoyed up by a force equal to the weight of the fluid displaced. If the milk sample is pure, then the lactometer floats on it and if it is adulterated or impure, then the lactometer sinks.
heat rises and cool air sinks
wait in the WI-FI plaza until the fire works come out. go to the back of the plaza and wait until the floats come out
