in which substance are molecules rigidly arranged?
a: the water in a freezer at -2c
b: the water in a cup at 22c (room temp)
c: the water in a pot at 100c
d: the water in a steam engine at 110c
The molecular in freeze water is more compact than room temperature water or boiling water, therefore, it would be harder to separate the molecules which makes it more rigid.
