"Is a pressurized air object heavier?
In other words, is an object heavier when it contains compressed air than when it's empty? For example, if I have a tire and weigh it before pumping it full of air, will it be heavier after it's pumped up? I say NO. A friend of mine insists it will be heavier once it's filled with air. Who is right? " Sounds to me like we have a long way to go with the "No child left behind" program. |

It doesn't make any difference that you end up stupid after bad instruction, it is more important that you not feel bad about BEING stupid. Something I have seen very commonly among our youth. Ever watch "Street Smarts"? One of the questions was, "How many people are in a trio"? Two of the people got it wrong. Sigh .................. Steve |
