Question

three laws of thermodynamics
the first law of thermodynamics says in any occurrence in the universe the total amount of mass & energy must be exactly the same before as after. for instance, it may appear that the wood burned in a fire disappears, but if you capture the air given off you can measure that every particle of wood lost is now a particle of air. also, any chemical energy lost is now heat. nothing is ever really lost.
the second law is less famous but equally true. it says entropy or chaos only increases in the universe. if you drop a spoonful of dye into water it will spread out everywhere but you can wait a million years and youll never see the dye bunch back into a droplet. if a hot object is next to a cold object. the heat spreads from the hot to the cold object.
the third law of thermodynamics says nothing is perfect. the only chaos - free or zero - entropy system would be a pure crystal with every atom stuck in a perfect position. while it is theoretically possible to make a completely pure crystal, it is scientifically impossible to stop all the atoms from shaking (absolute zero temperature.)
answer each question as the 1st, 2nd or 3rd law of thermodynamics:

1. which law tells you that if an object falls from a high location where it has 100 j of potential energy, it must get faster as it falls eventually gaining 100 j of kinetic energy and heat? ________
2. how do you know smoke in a room will spread out? ________
3. if the temperature inside a refrigerator decreases, the heat must have been pushed outside the refrigerator (the heat didnt disappear)________
4. how do you know that wood will burn into air but air wont unburn into wood? ________
5. if your friend tries to tell you shes perfect, how do you know shes lying? ________
6. if a magician pulls a rabbit out of a hat, you know the rabbit was definitely somewhere to begin with, the magician didnt create a rabbit out of thin air. ________

Explanation:

1.

The first law of thermodynamics states that energy (and mass - energy equivalence) is conserved. Here, the potential energy is converted into kinetic energy and heat, showing energy conservation.

The second law of thermodynamics states that entropy (a measure of disorder) increases. Smoke spreading out increases the disorder (entropy) of the system (the room).

The first law of thermodynamics implies that energy is conserved. The heat didn't disappear from the refrigerator; it was just transferred outside, showing energy conservation.

Answer:

1st law
