AP EAMCET · PHYSICS · Thermodynamics
First law of thermodynamics is represented by
- A \(d Q=d U+d W\)
- B \(d U=d W+p d V\)
- C \(d W=d Q+d U\)
- D \(d U=d Q+p d V\)
Answer & Solution
Correct Answer
(A) \(d Q=d U+d W\)
Step-by-step Solution
Detailed explanation
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.
