to answer truly i need to know "better then what?" however all water has some oxygen in it and it has very little effect on plant germination
wrong answer---It has oxygen in it
Depends upon how hot. Not too hot is fine, but too hot would kill the plant.
Yes. Tried this experiment and the plants in the dark germinate and grew faster than the plants in the sunlight. But, if you leave it in the dark for too long, its leaves would turn yellow from the lack of chlorophyll and the plants would eventually die. (I tried with green bean plants, so not sure if other plants can) By the way, you will have to make sure that the plants in the dark have enough air and water, if not it will probably die before germinating.
No, mung beans require water to germinate and grow. Without sufficient water, the seeds will not sprout or develop properly. Adequate watering is essential for successful mung bean cultivation.

Water, why would the plants get healthy if you peed on it?
because boiling water would cause the cells of the seed or plant to rupture, effectively killing the plant - this would be the same for all plants and seeds, not just beans
you would get tastier, better food. plants would die
Germination fertilizers seeds and helps them spread. Without it many plants would not be able to produce babies.
It depends upon the type of the plant. All the plants do not survive in salty water, few of the species of plants do. They are called Halophiles that grow in salty water they are not harmed by the salty water.
Water current is always in one direction so the seeds will germinate in the same place--disadvantage When the seeds germinate, they would have a source of water near them--advantages
Seeds would not be able to root in soil, so the plant would not be able to germinate, or begin growing.
There are a lot of different types of plants, but I recommend filtered water (fresh) for carnivorous plants and I'm guessing tap water (fresh) would be fine for normal potted plants. But make sure you don't have too many chemicals in your tap water.
