Gases
Plasma
The pressure inside the syringe will decrease if we move the plunger in:
Direction A
Direction B
We don't have to move the plunger as the pressure will change on its own.
None of the above answers.
Weather balloons travel to a great height gathering data before the balloon bursts. This is because the atmospheric pressure (layer of gas surrounding the earth):
Increases the higher you travel.
Decreases the higher you travel.
Remains the same.
Not enough information to answer the question.
