Phases
This is another way to say "state of matter"
What is phase?
This is when a liquid turns into a solid
What is freezing?
This is when a substance or material only changes its appearance and does not change its chemical composition
What is physical change?
This is the basic building block of all physical matter
What is an atom?
DOUBLE JEOPARDY!!
This is a graph that measures how temperature increases over time.
What is a heating curve?
This phase has particles that are spread far apart and moving very quickly
What is a gas?
This is when a liquid turns into a gas.
What is evaporation?
What is chemical change?
DOUBLE JEOPARDY!!
These are unique types of atoms that are listed on a periodic table in every chemistry classroom.
What are elements?
This is when two or more atoms are stuck together and cannot be easily separated.
What are molecules?
This phase usually only turns into a liquid, but on rare occasions will turn directly into a gas
What is a solid?
This is when a gas turns into a liquid.
DOUBLE JEOPARDY!!
This type of change occurs when solid ice melts into liquid water, and then evaporates as gaseous water vapor.
What is a physical change?
This is when every unit within a container is the same kind.
What is a pure substance?
This substance can be broken down into a new substance by chemical means.
What is a compound?
This phase takes the shape of its container and has fluid-like movement
What is a liquid?
DOUBLE JEOPARDY!!
This is when a solid turns directly into a gas.
What is sublimation?
This type of change could include two liquids mixed together and shortly thereafter, fizzing and bubbling occurs.
What is a chemical change?
This is when two or more atoms of different elements are stuck together
What is a compound?
In a heating curve, this is always increasing among particles and their movement.
What is potential energy?
DOUBLE JEOPARDY!!
This phase is only found in superheated matter where atoms form ionized gas particles
What is plasma?
This is when a gas turns directly into a solid.
What is deposition?
This solid powder forms after mixing two liquids together and is a sign of a chemical change.
What is a precipitate?
This is when you have multiple units of several atoms of different elements stuck together. Each unit is the same combination of these atoms.
What is a pure substance of a compound?
In a cooling curve, this is decreasing among particle movement UNLESS there is a phase change occurring.
What is kinetic energy?
