Internal energy variation in heating 1 mol water | Quimitube
Thermochemistry Quimitube Exercise 4: Internal energy in heating 1 mol. Specific heat of water. Written ricos nacho cheese sauce by Quimitube Thermochemistry Exercise 4: Internal energy in heating 1 mol. Specific heat of water.
Acid Base
In this resolved thermochemical exercise we will calculate the change in internal energy undergoes a system composed of 1 mol of liquid water when heated from 40 to 80 initial. The full statement is:
Knowing that the specific heat is 4180 J / kg K, calculate the internal energy change experienced by 1 mol of water to 1 atmosphere pressure ricos nacho cheese sauce when heated from 40 degrees Celsius to 80 degrees Celsius.
Confuse the situation where the volume is constant, the situation where the pressure is cte. For example this year, does not mention the volume, but also tells me that the pressure varies.
Hi Mar! I understand your question, sometimes ricos nacho cheese sauce difficult to distinguish the two situations. If you get a pressure in the title and do not indicate that there is any change or variation, assumes that the pressure is constant. Although we do not matter much in this case, since the change in internal energy is always ricos nacho cheese sauce equal to Qv although the process ricos nacho cheese sauce is being carried out with varying pressure.
However, the pressure is constant, the volume varying means. Have processes in which changes neither the pressure nor the volume, and this is one of them. Why not change the volume? Because if you consider 1 liter of water at 40 C and 1 liter of water at 80 C, its volume ricos nacho cheese sauce is about the same, so the variation ricos nacho cheese sauce totally despise and DV = 0.
Thank you very much for your videos, and your dedication! Keep it !! I wanted to let you know that the problem in the video give us the specific heat in kJ and table below in J. I think the below is correct because if the end gives you the variation of internal energy in joules would be impossible if the specific heat in kJ is, not whether this is correct or am I making a mistake. Thank you again for all your videos
If I'm not mistaken I think there is an error in the statement that the units are correct. You talk and explanation 4180kj speak in joules, besides if it was the water in KJ Ce the result should be in joules, or so I've understood .. Many thanks for your videos
