Question

Can a process on an ideal gas be both adiabatic and isothermal?

✓

Answer

No,
In a system either temperature varies or it heat varies.
In case of ideal gas Internal energy is function of temperature only thus for isothermal process change in internal energy is zero.
Now, since process is adiabatic thus heat exchange is zero.
therefore, work done is also zero.

A barometer correctly reads the atmospheric pressure as 76cm of mercury. Water droplets are slowly introduced into the barometer tube by a dropper. The height of the mercury column first decreases and then becomes constant. lf the saturation vapour pressure at the atmospheric temperature is 0.80cm of mercury, find the height of the mercury column when it reaches its minimum value.
