3
The molecules found in the ice cream mixture
are larger than those of liquid nitrogen
are moving slower than those of liquid nitrogen since biological molecules are larger than nitrogen
are organic molecules
include protein, carbohydrates, and fat molecules
include water
4
Thermodynamics is a branch of chemistry which studies
heat changes
how fast a reaction occurs
energy changes
how much chemicals cost
how many flavors are necessary to make something taste good
5

in all ways
6
In this demonstration the cryogen
is the ice cream mixture
boils away and is not found in the final ice cream product
is used to freeze the ice cream mixture
is gaseous nitrogen
is liquid nitrogen

100 degrees Celsius
98.6 degrees Fahrenheit
37 degrees Celsius
8
The ice cream mixture contained
cream
half-and-half

When ice cream melts
its heat moves to the environment
heat from the environment moves into the ice cream
the cold of the ice cream moves into the environment
the cold of the environment moves into the ice cream
the air must be cooler since the ice cream is getting warmer

Liquid nitrogen
is made from the air
is non-toxic
is extremely cold
will support life
will burn
