Do all the molecules of a gas at a given temperature have the same kinetic energy?
1 Answer
No
Explanation:
The average kinetic energy at a given temperature will be the same value. A gas at room temperature - Some move faster, some move slower, and their average will always be the same at that temperature.
Imagine a classroom full of kindergarten kids running on the track. Some are faster, some are slower - but their average kinetic energy will be some certain value.
Now if you heat the room up, then the gas molecules move on average faster, with some being even faster and some being even slower.....but their average is faster.
12th graders = higher temp gas.....kindergarten kids = lower temp gas
If i take a class full of 12th graders and take them to the track, they'll on average be faster than the kindergarten kids. However, some 12th graders will be very fast, and some will be slower than the kindergarten kids, but they'll on average be faster.
