Want this question answered?
"Force the substance into a smaller volume" is pretty much the definition of "compress".
No magnetism is not matter it is a force of energy caused by perpendicularly(sorry for the big word)aligned poles in specific metals. Magnetism is also caused by rapidly churning metals. Short answer: No
Decrease the pressure of the surrounding environment. Thus, the force acting on the balloon from the outside decreases, allowing the air pressure that creates a force inside the balloon to have less of a counteracting force.
The total force of the molecules hitting the walls (Pressure) will decrease if the volume is increased and the temperature stays the same. From PV = nRT, one can see that as V increases, P must decrease to maintain the same T.
The conditions for 'something' to be called matter are :- 1. It should have mass and volume. 2.It should have intermolecular force of attraction 3.It should be made up of particles. If these conditions are present, then 'something' can called matter.

"Force the substance into a smaller volume" is pretty much the definition of "compress".
If the matter can be compressed into a denser material by this force, yes.
I think its gravity caused by weight.
No, volume is dependent on things such a temperature and pressure. Most things contract (have a smaller volume) when they are cold and expand (have a larger volume) when they are hot. Also, if you apply pressure to a solid or a gas, you may decrease the volume. This is what happens when you put air in your tires - at some point the tire cannot expand, so you have to use pressure to force more air into the same volume.If you were to dive down to the deepest part of the ocean, the pressure from all that water on top of you would crush you, and your volume would decrease.
contraction. Compression is often used when an external force is being applied to reduce the volume of the object.
weight weight(kg)=mass(volume) +gravity(N)
Gravity and nuclear force
I think its gravity caused by weight.
Real forces have its origin in matter such as electricity,gravitation etc.Pseudo force is caused by inertial motion such as centrifugal force.
