As tool and work are not in contact in EDM process
Your Answer : (Not Answered)
Correct Answer : D
In EDM, the thermal energy is employed to melt and vaporize tiny particles of work-material by concentrating the heat energy on a small area of the work-piece. A powerful spark, such as at the terminals of an automobile battery, will cause pitting or erosion of the metal at both anode & cathode. No force occurs between tool & work.
Which among the NC operations given below are continuous path operations?
Arc Welding (AW), Drilling (D), Laser Cutting of Sheet Metal (LC), Milling (M), Punching in Sheet Metal (P), Spot Welding (SW)

When heat is imparted to a system,
Your Answer : (Not Answered)
Correct Answer : C
As heat is given to a system, its internal energy increases, thus increasing the entropy of the system.
Only those processes are possible in nature which would give an entropy ____ for the system and the surroundings together.
Your Answer : (Not Answered)
Correct Answer : B
The entropy of an isolated system can never decrease.
The proof that work done in all reversible processes is same can be done by violating Kelvin-Planck statement.
Your Answer : (Not Answered)
Correct Answer : A
During the proof, we end up violating the Kelvin-Planck statement.
