- MCQ
Given below are two statements. One is labelled as Assertion A and the other is labelled as Reason \(R\). Assertion \(A\) : If \(dQ\) and \(dW\) represent the heat supplied to the system and the work done on the system respectively. Then according to the first law of thermodynamics \(d Q=d U-d W\). Reason \(R :\) First law of thermodynamics is based on law of conservation of energy. In the light of the above statements, choose the correct answer from the option given below :
Pick an option to check your answer.
Answer & Solution
Correct Answer
(C) Both \(A\) and \(R\) are correct and \(R\) is the correct explanation of \(A\)
Step-by-step Solution
Detailed explanation
First law of thermodynamics is based on law of conservation of energy and it can be written as \(dQ = dU - dW\) where \(d\)W is work done on the system
