How could you keep a balloon from rising or falling in air?
You can keep a balloon from rising or falling by adjusting its internal pressure to match the external air pressure. If the internal pressure is the same as the external air pressure, the balloon will stay at the same altitude. Additionally, you can attach a weight to the balloon to counteract its natural tendency to rise.
What is the difference between pressure and stress?
Pressure is the external force acting over a unit surface area of a material. Stress is an internal force acting over a cross sectional area within the material. It may also be thought of as the internal resistive response of a material to the applied external pressure. They both have the units of force / area. think it as- suppose we have a cubical solid mass. we apply external force of few magnitude on it and this force will try to deform the cube. at the same instant an internal force will generate within the cube that will try to maintain the shape and size of the cube i.e. this internal force will work against the applied external force. this induced force within the cube is stress.
What is the external pressure?
External pressure is the force exerted by the surroundings on a system. It can affect the behavior and properties of the system, such as in chemical reactions or phase changes. External pressure can influence the equilibrium position of reactions and the physical state of substances.
The temperature at which the vapor pressure of a liquid is equal to the external pressure is the what?
The temperature at which the vapor pressure of a liquid is equal to the external pressure is known as the boiling point. At this point, the liquid changes to a gas by overcoming the external pressure.
How are external forces related to internal forces?
External forces act on an object from outside its system, while internal forces arise from interactions within the system itself. External forces can change the state of motion of an object, while internal forces contribute to the object's stability, structure, and internal interactions. The overall behavior of an object is determined by the net effect of both external and internal forces acting upon it.
How does the difference in external pressure to internal pressure of the rocket affect it's distance?
The difference between external pressure and internal pressure in a rocket influences its ability to ascend and maintain stability. If the internal pressure is significantly higher than external pressure, the rocket can generate thrust effectively, allowing it to travel greater distances. Conversely, if external pressure exceeds internal pressure, it can result in structural stress or failure, limiting the rocket's range and potentially causing it to descend prematurely. Thus, managing this pressure differential is crucial for optimizing flight performance and distance.

What are possible internal and external influences on your food choices?
The possible internal and external influences on your food choices include; External: advertising peer pressure aroma ease of access Internal: general hunger perceived deficiency (yearning for a particular food or flavor)
Is bearded dragons development internal or external?

Why does the eardrum may burst inwardly if you are in a deep sea but it may burst outwardly if you are in space?
In the sea, the external water pressure is greater than the ear's internal air pressure, so it implodes. In space, the external vacuum is less pressure than the ear's internal air pressure, so it explodes (or is 'sucked' into space.)
Can water pressure kill a human?
Our bodies have an internal pressure equal to that of the atmosphere (101000 pascals). Once the external pressure on you body exceeds this internal pressure enough your body will implode. This external pressure can be provided by water. Depending on how you go about going that far below water and the specific tolerances of your body a deadly depth can be from 500 to 1200 feet.

How does the octopus prevent brain damage despite the lack of a rigid braincase?
Octopus internal pressure equals external pressure and there is no crushing.
