First law of thermodynamics is represented by

First law of thermodynamics is represented by
  1. \(d Q=d U+d W\)
  2. \(d U=d W+p d V\)
  3. \(d W=d Q+d U\)
  4. \(d U=d Q+p d V\)

Solution

According to first law of thermodynamics, \(d Q=d U+d W\) where, \(d Q=\) heat supplied to the system , \(d U=\) change in internal energy of the system and \(d W=\) work done by the system.
