Question

Which of the following situations would violate the second law of thermodynamics?

A. Ice melting in a glass of lemonade on a hot day
B. A cup of lemonade turning to ice in freezing weather
C. A glass of lemonade starting to freeze in a warm room
D. Lemonade being frozen into ice in a freezer

Answer 1

C. A glass of lemonade starting to freeze in a warm room.

Step-by-step explanation:

This is because there is no source of cold to properly freeze the lemonade, freezing happens when a cold source starts to slow down the movement of atoms. So if there's nothing there to freeze it, it can't freeze.

Alternatively, there are some materials that harden when not subjected to heat, but that's not freezing. It's just cooling.
