Hello, the question statement says that one mold of helium gas is heated from 27 degrees celsius to 327 degrees celsius at constant volume, find out the heat change.
00:19
So we have helium gas that is one more which is heated from 27 degrees celsius to 327 degrees celsius, we have to find out delta.
00:50
So as we know, delta q is equal to at constant volume.
01:03
So delta q at constant volume is equal to n, cv, delta, t, where n is equals to number of moles, cv refers to the molar specific heat capacity and delta t refers to the change in temperature.
01:42
Putting the value of these here, we get the value of delta q.
01:48
So one into cv.
01:51
So we actually find out the value of cv.
01:55
So cb is equal to f by 2r, where r is a degree of freedom...
