A. gas change, color change, and temperature change.
B. color change; one day you wore a ring that wasn't stainless steel in the shower, so the following morning it was rusted.
The answer is 0.492 because there are 100 meters in a hectometer, and 49.2/100 is 0.492
the air molocules that are surrounding the metal will speed up, and the molocules in the metal will slow down, because as the metal cools the molocules will cool which would make them slow down, but then it would heat the surrounding air and make those molocules speed up.
Let's see
- ∆S refers to the total change in entropy of system.
Graphite was in solid state and oxygen was in gaseous state.
When they synthesized they converted to gaseous state
- So randomness of particles increases
- So entropy also increases
∆S=+ve
