Hi,
I have a little conceptual question. I have an idea about the topic, but I would need to formalize it a little bit.
The problem is the following:
Imagine the following scenario: You put a little bit of water in a bottle, you assure yourself that everything as at a constant temperature and measure the temperature of the water with a thermometer. You close the bottle and shake it as hard as you can during some minutes. When you are tired and feel that you can't go on, you continue to shake the bottle for a few minutes more. After this you measure again the temperature. Make an estimation for the change of temperature.
Well, if I'm not mistaken, the shaking should count as work. The system should be a classic hydrostatic system and so the thermodynamic coordinates are P, V and T. So I'm doing some work over the system, the volume stays constant. What happens with the pressure, does it stay constant or does it change?
And with respect to the temperature, I would say that it increases. But I do not know how to answer the question the correct way and so that it sounds good.
Maybe you can help me.
