beks73 [17]
It's depending on what size of the tree it is. For example, if the tree is large it will block most of the water that runs through. If the tree is small it shouldn't do as much besides block a little amount of water and it will probably go down stream.

Water could be made to boil lower than its normal boiling point of 100 degrees Celsius at 92 degrees Celsius by?
KonstantinChe [14]
Water could be made to boil lower than its normal boiling point of 100 degrees Celsius at 92 degrees Celsius by lowering the atmosphere or external  pressure.

The boiling point is the temperature at which the vapor pressure of liquid equals the external or atmosphere pressure.

So, if you decrease the external pressure the temperature needed for the liquid reach the lower external pressure is also lower..


You can accomplish by taking the water to higher levels in the Earth (atmosphere pressure at high altitudes is lower than at sea level) or by creating vaccum.

Matter is a physical substance that occupies space.
Lets say you put random stuff in a box. That stuff is matter, filling the box.
Its common to say that matter is everything around you. You can see everything around you (almost).
