Answer:
Explanation:
An increase or decrease of energy could have caused the liquid methane to change phase.The lake disappeared during Titan's summer, when the amount of energy being transferred into the lake was higher than at other times, so the lake must have evaporated, not frozen.An increase or decrease of energy could have caused the liquid methane to change phase. If the energy increased, this would have caused the kinetic energy of the molecules to increase, and possibly their freedom of movement to increase.
