Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
The first law of thermodynamics states that the total energy of an isolated system is constant; energy can be transformed but not created or destroyed. It is expressed as \( \Delta U = Q - W \), where \( U \) is internal energy, \( Q \) is heat added, and \( W \) is work done by the system.
Answer: energy.
Answer: energy.
