Based on the first law of thermodynamics, which one of the following is correct ?

Answer»

For an ISOTHERMAL process,`q=+omega`
For an isothermal process ,`DeltaU`=-q
For an adiabatic process,`DeltaU`=-w
For an adiabatic process,q =-w

Solution :BASED on the first law of a cyclic process is zero,i.e., `DeltaU`=0.
`therefore` q=-w
