space
Mass and energy always have locations in both time and space; the amount of space that they take up depends upon their density, but they do take up some. Since energy is often associated with matter (heat, kinetic energy etc.) it would be the matter that takes up the space. The energy would be in the same space as the matter. But energy can also exist independently of matter (such as a photon of light travelling in space) and in that case, the energy takes up space.
No, the amount of force required to lift a load can vary depending on factors such as the weight of the load, the distance it needs to be lifted, and the presence of any friction or resistance. A heavier load or a greater distance will typically require more force to lift.
Not necessarily. Two objects with the same mass can have different densities, meaning one object could be more compact and take up less space than the other object even though they have the same mass.
I think logically, because its volume doesn't expand much when it heats up. If I take a pan of melted chocolate, and let it go cold and solidify, it won't take up appreciably less space, and it will still weigh the same amount... still have the same mass. I recall that water is a bit of an exception though, and it's maximum density (ie. it's heaviness by volume) is at 4 degrees. That should mean if you take a jug of water, which is ready to overflow at 4 degrees, it will already be spilling over if you warm it a bit or freeze it.
Nothing, if it is the same amount of material in all three phases.If however it is the same volume and pressure then solid and liquid phases will have about equal mass but the gas phase will have much less mass.
Space
A solid always takes up the same amount of space, or volume, unless it undergoes a physical or chemical change. This is due to the arrangement of particles in a solid being tightly packed and maintaining a fixed shape and volume.
The same amount of water occupies the maximum amount of space in gaseous state, lesser in liquid and the least in the solid state.
No. A solid has a definite volume no matter what container it is placed in.
Yes. A solid has a definite shape and volume. A liquid has a definite volume, but an indefinite shape. A gas has neither a definite shape or volume.
homeostasis
When there is the same amount of leeches and peers on a torrent, the file may take longer to download.
They have the same volume.
Roughly the same amount it would take to kill you.
The same amount of time it take to grow
Provided one does not place the solid in extreme gravity fields, yes.
I do and I lost a good amount of weight in a short amount of time.
