Think about what you already know about different
phases of matter. Given this figure showing the
process of changing from one phase to another, what
parameter (physical quantity of a system) serves as an
indicator for energy flowing into or out of the
molecular system?
Gas
Cool or
compress
Heat or
reduce
pressure
Liquid
Cool
Heat
Crystalline solid
In the box below, make a claim as to which parameter
is represented in the processes in the figure and use
your ideas of energy to support your claim.
排
Solid
Liquid
Gas
If you are changing states of matter from gas --> liquid
--> solid, what happens to the energy?
O These processes require energy from the
surroundings to break attractions between
molecules.
O These processes release energy to the
surroundings to form attractions between
molecules.
O These processes release energy to the
surroundings to break attractions between
molecules.
These processes require energy from the
