What might happen to the blood of an astronaut subjected to extremely low pressures?
it would boil due to the vapor pressure properties of blood
Metamorphic rocks were originally igneous or sedimentary rocks. They were altered by being involved in an episode of mountain building, buried deep and subjected to immense pressures and temperatures. In effect they were the roots of the mountains. Later erosion over millions of years removed most of the mountains leaving the altered rocks for us to see.
Peer Pressures? In home school peer pressures are none existent. Siblings hang out with each other, and dad is always "fairly cool". But of course fights will still happen... it isn't paradise. The only real peer pressures are those around friends after school hours. But since you spend your time with your parents those pressures never amount to much.
What might happen if an astronaut floating in space moved the north poles of two magnets together and let them go?
Not very much unless it is also mixed with water and subjected to high temperature and pressure to prevent the water boiling. This reaction is used as part of a method for extracting aluminum from bauxite ore. At normal temperatures and pressures, aluminum oxide will dissolve slowly in sodium hydroxide solution to form various complex sodium aluminum hydroxides.
When a 75 kg astronaut in space pushes against a 200 kg anvil what will happen when the astronaut lets go of the anvil while pushing it?
Since the anvil is more than twice as massive as the astronaut, the astronaut will move much more rapidly than the anvil, as they both move in opposite directions following the astronauts push. And chances are, the massive anvil with then collide with the astronaut's spacecraft, doing horrendous damage, and the foolish astronaut will then be unable to safely return to Earth. So when you are in outer space, be careful with your anvil. I…
