Chapter 1
What disappeared on Saturn's moon, Titan?
Lake
What happened to the Lake on Titan?
Evaporated.
Does the molecular attraction of a substance ever change?
No, it always stays the same.
What planet did we go to?
Mars.
What are the three phases of matter?
Solid, Liquid, Gas
James put a pot of liquid water on a hot stove. When he came back, the liquid was gone. What happened?
Liquid changed phase into gas through evaporation.
What does Molecular Attraction mean?
What are the disease-causing agents that your astronauts were infected with? (one word)
Pathogens.
What is it called when a substance changes phase from solid to liquid?
Melting.
What does Freedom of Movement mean?
The way molecules move around each other.
If a substance has a strong molecular attraction, what phase is the substance?
Solid.
What are the robots called?
Edison.
What do water molecules do when solid?
Can only move in place.
If a substance has fast freedom of movement, what phase is the substance?
Gas.
Would a substance need more or less energy to change phase?
More energy.
What are the astronauts trying to do on Mars?
Set up a habitable space.
What is it called when a substance changes phase from gas to liquid?
Condensation.
What does kinetic energy mean?
The energy an object has because it is moving.
Why does an energy transfer not always result in a phase change?
Depends on the amount of kinetic energy and molecular attraction of the substance.
What is the key called when finding what your astronaut was infected with?
Dichotomous Key.
