Author | Topic: a cup's weight depends on the time you hold it. | |||||||||||||||||||||||||||||||||||||||||
dandon83 Inactive Member |
A 50 gramms water-cup can weigh twice than that if you hold it for 15 minutes ,and can be 1000g if you still hold it for an hour , and you might need an ambulance if you hold it for two days.
So do not give your proplems more weight than they realy are (by keeping thinking about them all the time) . Put your problems aside and take a rest there are many important things to be done.

The science may not be there, but there is a good message in what Dandon says.

There is something I want to comment on this. If you hold such a cup for 15 minutes the first time, it will certainly feel twice as heavy. HOWEVER, after you've been to the hospital, back, and well rested, chances are that it will take you 20 minutes to start feeling tired. 3rd time around, it will take you 25. And so on and so forth. I am one of those that would rather do things the hard way if the easy way is not needed. I never take medicine for colds and other minor illnesses. I run everyday. Sure, after a marathon run my legs may feel a little sore. BUT, I know that my immune system is slightly better than before and I am slightly stronger than before. Same thing with my brain. Everyday, I take it out and bounce it around like a basketball. Who knows? One day when the earth suddenly stops rotating, I could be the only one that doesn't get a massive concussion. The Laminator

16 cups =1 gallon
1gal H2O=8.34 lbs. H20 8.34 lbs H20=3.78 kg H20 3.78kg H20=378g H20 378g H20 divided into 16 cups H20 -----> 23.62 gramsH20 in 1 cup +26.37g coffee cup =50 grams total weight If evaporation of water vapor at a given relative humidty and temperature and barometric pressue is taken into the equation post 1 hour the weight of the water will be less. I leave this to our resident physics experts to calculate the amount of H20 lost to evaportion post 1 hour. And what will the final weight in grams would the water be? It is a bugger of a calculation. Any takers? "One is punished most for ones virtues" Fredrick Neitzche

It is a bugger of a calculation. Any takers? This is, indeed, a bugger of a calculation. However, we are lucky because rate of water evaporation isn't determined using weight. It seems like taking Arizona as a reasonable examine would do, where a general evaporation rate of a third of an inch per day is estimated, which would mean a week or so. Since I don't think we have a volunteer that wants to stand around looking silly, you can also just leave a glass of water somewhere and see. Btw, without mucking about too much with determining the surface area of a paper cup, I'd say about 1.4 grams per hour in evaporation without heating...

quote: This is also a good lesson on the inadequacies of the human senses with relation to reality. Even though the cup FEELS like it is getting heavier, it is only through the scientific method that we know that it is actually getting lighter. Therefore, common sense at it relates to human perception is unreliable in describing reality. This invalidates the concept of percieving a creation through human perception alone, or in detecting intelligent design.

I believe everything was created yesterday (Tuesday) so I might need that ambulance tomorrow.

From what was written, why would you think there is any water in the cup? ;-)

You're sharp Trae! I felt there was something out of kilter as I read the thread, but it was when you posted your message that I realised that there was no mention of water. I wonder if it was intentional?

The perception of increased weight is related to the uild-up of fatigue toxins in the muscles. As pointed out above, this is an atrtifact of human percpetion, not a property of wehatever mass you are supporting. A Cup - water filled or not - supported by a metal beam will not be experienced as growing heavier by that beam. Obviously.
