The Law of Conservation of Matter

When you eat a burrito, where does all that matter go? What about when matter changes phases, does any matter appear or disappear? When we talk about this sort of stuff, reality sometimes goes against our intuition, so we'd better make sure we get the science right! Check it out.

Apologies for two errors, at 1:01 I should have omitted the word "other", as obviously any phase change is a mere physical change, and then later with the pipe, oxidized copper produces a patina, not rust. Sorry about that!

I want to ask a question
Matter can be destroyed by antimatter and release photons (photons are not matter)
Can the law of conservation of matter be wrong?
Thank you

@@rosesdamour4775 matter is really just super dense energy, so in reality youre not destroying any matter

How does carbon get into an embryo, and eventually to a newborn. DNA is replicated, so I’m having a hard time visualizing this.

[@PurEvil10]

This is not a fundamental conservation law, because matter can be converted to energy according to Einstein's equation, E=m.c.c. The law of conservation of energy is actually a fundamental law.
However, in chemistry the energy released in chemical reactions are very much smaller to be considered for mass-energy relationship.

[@minimoulah]

We will never un out of water which is one of the biggest lies ever told to mankind. In fact, according to this Law the Earth can never run out of any resources.

When a pot of water is boiled, the vapor collected will have __the same_____ matter than the water had.
The law of conservation of matter states: matter is not ___created_____ or _destroyed_______ in any physical or chemical process.
When water is boiled what happens to the water molecules when they turn into water vapor? ____they speed up and move away___
Conservation of matter applies to which two physical processes? __phase changes and chemical reactions_____
When looking at balanced equations, the atoms have __the same numbers of each atoms on each side.
When things rust, oxygen atoms from the air will form a _new _covalent ____ bond with the copper pipe.

[@prabuddhashrestha]

Quick question
If you boil salty water and collect the steam....probably the mass of the water before boiling and mass obtained from the steam would be different right?....

[@ProfessorDaveExplains]

well yes certainly, the salt will stay behind! that's distillation essentially.

Hi, I'm curious about the distinction and definitions of mass and matter? If you burn a tree (matter) inside a vacuum chamber and reduce it to its component elements, could the tree (matter) be said to have been destroyed?

[@ProfessorDaveExplains]

Well the tree has been destroyed, but no matter has been destroyed, it just changes forms, as with any chemical reaction.

[@kari2745]

So since no matter has been destroyed will the mass be the same before and after burning the tree?

[@RobbyGAMEZ]

@@kari2745 Mass of the tree is retained in the CO2 and H20 released during combustion along with other compounds leftover or burned incompletely. These include Carbon Monoxide (CO) and leftover carbon in the ash, charcoal, and smoke.

[@boethia7367]

Thank you!

[@CristobalAtria]

The steam would have just a liiiiiiiiiiiittle more mass because of the temperature, because of Einstein, because of e=mc^2, same amount of matter like in atom count, anyway. Right?

[@ProfessorDaveExplains]

hmm, to my knowledge in an idealized scenario, the masses should be identical!

[@creativityking4649]

No, because temperature as energy is utilised in phase change so mass will be literally same.

[@JNCressey]

Yes, a little.
Say we started with 1kg of 0°C liquid water, and heated and boiled it into 200°C steam.
The extra energy it would have is 1 kg * 100°C * 4.186 J/g/°C + 1 kg * 2260 kJ/kg + 1 kg * 100°C * 2.010 kJ/kg/°C
= 2.88MJ
The equivalent mass is 32 ng, or a defect of 0.0000000032% of the mass we're measuring.
But my kitchen scales only read 3 significant figures.

I'm confused, you said the mass doesnt change but the mass of the pipe changed when it became rusty.

Because oxygen atoms are being added to it.
