### Calculating change in entropy from 1st and 2nd laws of Thermodynamics

In the Learning Outcomes for thermodynamics, it lists that we should know how to calculate change in energy and entropy from the 1st and 2nd laws of thermodynamics. How do we calculate entropy with the first and second laws?

1st law of Thermodynamics deals solely with energy and isn't related to entropy nor can it be calculated from it.
