Phase Trivia
What is solid?
What are Titan Lakes filled with
What are ethane and methane?
The way molecules move in a liquid.
What is around each other?
A noticeably different form or state of the same substance.
What is a phase?
This phase looks rigid.
What is a solid?
The phase after liquid evaporates.
What is gas?
After 2007, the sun transferred enough energy that the kinetic energy of the methane molecules increased enough to overcome the attraction between them. Why did the Lakes Disappear?
What is evaporation?
In this phase, you might say molecules shiver.
What is a solid?
The energy that an object has because it is moving.
This phase has no visible shape, as if it vaporized.
What is a gas?
Water is in this phase at -20C.
What is solid?
Can you swim in Titan's lakes? Why or Why not?
In Titan’s lakes, your body would be much denser than the liquid methane you’d be attempting to swim in. It would feel as if you were made of stone. The lakes are made filled with Ethane and Methane.
The time when molecules stop moving on Earth.
What is never?
The way molecules in a substance move around relative to each other.
What is freedom of movement?
The pull molecules have that is always the same.
What is molecular attraction?
Methane is in this phase at -100C.
What is gas?
The sun did this to the lake.
What is add energy?
In this phase, molecules move like dancers in a mosh pit.
What is gas?
The scale where we can see things with our bare eyes.
What is macro-scale?
This phase flows to take the shape of containers.
What is a liquid?
Or in some cases
What is a gas?
The phase when enough energy is removed from a gas.
What is liquid?
Why do you think scientists are interested in liquid lakes and oceans on Titan?
Titan's rivers, lakes, and seas of liquid methane and ethane might serve as a habitable environment on the moon's surface, though any life there would likely be very different from Earth's life.
Molecules are NOT moving in place.
What is liquid? OR What is a gas?
The average kinetic energy of the molecules in a substance.
What is temperature?
The phase after you add energy to a solid, and molecular attraction is greater than kinetic energy.
What is the same phase, a solid? Or what is a liquid?
