Energy cannot be created or destroyed, then where does it go when cooling or heating over time?
In: Physics
If you had a glass of salty water, and placed that glass in a full bathtub. Come back in a little bit, and sample the water in the glass. It is a lot less salty.
Where did the salt go?
Just like heat energy, it simply spread out. Whatever environment (water, air, other objects) it spread into got warmer because of it. But if, say, we’re talking about the atmosphere, that “bathtub” is so huge that the difference is negligible.
