Question

piston-cylinder device initially contains 0.6
kg of water with a volume of 0.1 m3 and
pressure of 800 kPa. The cylinder is
connected through a valve to a supply line
that carries steam at 5 MPa and 500 degC.
Now the valve is opened and steam is
allowed to flow slowly into the cylinder until
the volume of the cylinder doubles and the
temperature in the cylinder reaches 250
degC, at which point the valve is closed​

Answer 1

Silk fibre is converted into silk yarns through spinning.

For an isothermal, reversible process, the work done by the gas is equal to the area under the relevant pressure -volume isotherm. It is given as WA→B=NkTlnVBVA W A → B = NkT ln ⁡ V B V A .a colourless volatile liquid with a planar unsaturated five-membered ring in its molecule.
