The condition \(d Q=d W\) holds good in which of the following ?
The condition \(d Q=d W\) holds good in which of the following ?
Adiabatic process
Isothermal process
Isochoric process
Isobaric process
Solution
According to first law of thermodynamics,
\(d Q=d W+d U\) ...(i)
For isothermal process, there is no change in internal energy.
Hence, \(d U=0\)
\(\therefore\) From Eq. (i), we get
\(d Q=d W\)
Hence, above equation holds good for isothermal process.
