This question arised from the description of enthalpy here https://www.quora.com/What-are-the-intuitive-explanations-of-internal-energy-and-enthalpy I am attaching the snipped that the author had presented there. I felt to create the system, we first need energy to create matter itself and...

but isn't the internal energy attributed to the Kinetic energy possessed by the atoms by virtue of the temperature or heat energy ?, so shouldn't the internal energy be zero at 0 kelvin. Therefore internal energy shouldn't contain the rest energy which is independent of temperature or kinetic...

Hi, I have been trying to understand what is enthalpy (H = U + PV). What has been my current understanding is it is the energy content in a system. And this nicely brings together the energy contents in terms of the 3 state variables, Temperature, Pressure and Volume. If enthalpy is the...

International basked ball games are played with a basket ball inflated to 8 PSI. But I am curious to understand how it can stay inflated when the atmospheric pressure is 14.7 PSI. So shouldn't the external atmospheric pressure overcome the pressure within the ball ? Shouldn't the air pressure...
