Answer:
the change in entropy is ΔS= 1.278*10^4 J/K
Explanation:
according to the second law of thermodynamics, and assuming a reversible process
ΔS= ∫dQ/T
where
ΔS= change in entropy
Q= heat exchanged
T = absolute temperature
for sensible heat
Q= m*c*(T-To)
c= specific heat , T= final temperature , To= initial temperature
therefore
dQ= m*c*dT
ΔS= ∫dQ/T = m*c*∫dT/T = m*c*ln (T2/T1) = Q* ln (T2/T1)/(T2-T1)
replacing values
ΔS= Q* ln (T2/T1)/(T2-T1) = 4.00 ×10^6 J* ln(318 K/308 K)/(318 K-308 K) =12780.64 J/K
ΔS= 1.278*10^4 J/K

Current in an electrical circuit can effectively be reduced to zero by inserting a very high resistance
Hi!
The correct answer is: C. It is the data value that appears the most often in the set.
<h3>
Explanation</h3>
The mode of a set of values is the number which is the most frequently appearing, or most repeating value in the range. The numbers that show one time each are
A - 16 , C - 25 , D - 3
While 13 appears three times with the dishes labelled
B , E and F
So, the value that appears the most times is 13, and hence 13 is taken as the mode of this data set
<h3>Hope this helps!</h3>
