For Open, expect a cut-off of some 190 minimum for the first round. However the cut-off scores depend upon many factors
Your Caste
Difficulty level of the paper: Every year the histogram of marks scored by all the candidates appearing the test will have some variation. Expect the average to be as less as possible for the cut-off to go down.
Timeline of admission process for NITs and IITs: As generally most of the students getting an admission to NITs and IITs will score pretty well in CET, they are always there to grab a seat in VJTI/COEP if the admission to NITs/IITs start after this process. But these students will later surrender their seat. So expect the cut-off to drop after the first round.
However, I suggest you not to score based on the cut-off. Try scoring as high as possible and then hope to get a seat you desire.

Mathematical formulation of first law of thermodynamics.
If heat q is supplied to a system, it may be used up partly to increase the internal energy of the system and partly to produce some mechanical work. If DE is increase in internal energy of the system and w is the work done by the system, then we will have,
q = DE + w
This equation is the mathematical formulation of first law of thermodynamics. It may be written in a number of other forms as follows;
DE = q w.
If the changes are very small, it may be written as;
dE = dq dw.
If the work done is the work of expansion only and the volume increases by a small amount dV against the external pressure P, then we know that dw = PdV
Therefore, E = q PdV.
From the above equation, it is clear that at constant volume I.e. dV = 0. The change in internal energy is equal to heat absorbed or evolved by the system.
