Answer:

0.1 J/K

Explanation:

entropy change equation is as followed:

[tex]\Delta S=\frac{\Delta Q}{T}[/tex]

where ΔS=entropy change

          Q=Heat transfer

          T= temperature

[tex]\Delta S=\frac{\Delta Q}{T}[/tex]

[tex]\Delta S=\frac{30}{300}[/tex]

[tex]\Delta S=0.1 J/K[/tex]

hence the change in entropy of system which is [tex]\Delta S[/tex]is equal to 0.1 J/K
