Does anyone know of any calculator apps that can deal with units? I know I can do it on google search, but I was looking for something more like a calculator. I found this one: http://physyapps.com but it's only for iphone and mac.
Thanks,
Paul
It is only convention (and history) that we have temperature as one of the 7 base SI dimensions. You are absolutely right that temperature can be derived from the internal energy and entropy. As others have said, temperature could have been replaced with another derived quantity, but...
Dr. Claude has it right. Sounds like a partial pressure problem. The total pressure is the sum of the partial pressures for each gas in the mixture. In this case, it is air (N2, O2, ...) + ethanethiol. I would assume ideal gas behavior (pV = nRT) and work from there.
