Sublimation (absorbs)
400
What is the law of conservation?
The mass/energy at the beginning of a phase change is the same as the end
400
True or false, physical changes are usually irreversible.
False.
500
It has a higher viscosity than water.
500
What is the molecular arrangment of plasma?
There is no distinct arrangment, it's like a ionized gas.
500
What phase change is it going from a gas to a solid?
Deposition (releases)
500
What's the difference between a solid crystalline and a solid amorphous state?
Crystalline states are organized a a crystal lattice while amorphous is a disordered arrangement of atoms
500
What is heat of fusion?
The amount of energy absorbed or released to change 1 gram from a solid to a liquid or vice versa.
