Question: Both cups are placed simultaneously in a constant −5 °C environment. After fully reaching thermal equilibrium, which outcome is most likely?
A. The left cup freezes solid; the right cup remains liquid.
B. The right cup freezes solid; most of the left cup stays liquid.
C. Both cups are completely frozen.
D. Water freezes at 0 °C, so at −5 °C both would have long since frozen solid.
Clues:
1. There are two glasses of clear liquid, each with an egg inside.
2. The egg in the left glass is suspended in the liquid.
3. The egg in the right glass is at the bottom of the glass.
