I don't understand your point there. Clearly pigs feet aren't conserved.
if you burn a pigs foot it is transformed into other stuff.
if you burn gas it is transformed into other stuff.
neither is destroyed.
so both are conserved.
and you cannot create pigs feet or gas.
So are you saying the 1st law is just made up?
energy is not a fuel of any type.
it is the result of a force.
if that force is gas or pigs feet or anything that burns burning under a boiler producing steam , or sunlight producing steam and then that steam produces a force then it is that force that is energy.
you cannot destroy a force. you can only transfer a force from one object to another object.
you cannot create anything , so you cannot create a force on a object that would transfer that force to another object.
the first law is 100% correct , its just used improperly as it is only used in thermodynamics and it applies to everything.
But in that case, how does it work?
when the bottle is squeezed the air at the top of the bottle is compressed and the pressure of the air and the water in the bottle both increase to the degree of pressure placed on the bottle by the force he is applying with his hands.
in a closed container pressure is equally distributed in all directions , this means that the water pressure surrounding the object is equal everywhere on its outside.
and buoyancy is due to a pressure difference at the top and the bottom of a submerged object , since there is no pressure difference there is no buoyancy.
and it sinks.
the object floats in the bottle because it is placed in the bottle at 1 atm.
he then places a cap on it , but the pressure remains at 1 atm.
it only sinks when the pressure in the bottle no longer differenciates.
Yes, but so what? If your hand had a little bit of bouyancy it'd float up.
does you hand float up when you go outside?
But if it's bouyant how did you get it down there in the first place? You had to consume a huge amount of energy pushing it all the way down.
a submarine floats on top of the water.
but if you release air out of the submarine , the submarine sinks.
all the way down to the bottom.
the reason they dont sink all the way down below their rated depth is because they dont allow all the air out of the submarine.
they intentionaly keep some compressed air inside to ballast the submarine at a desired depth.
or to obtain neutral buoyancy under water.
do you have a physics book?
