Answer:
#1=A, B, C
#2=When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. ... Solids, liquids and gases all expand when heat is added.
Explanation:
#1-One example of deposition is the process by which, in sub-freezing air, water vapor changes directly to ice without first becoming a liquid. ... This causes the water vapor to change directly into a solid. Another example is the soot that is deposited on the walls of chimneys.
#2-When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. ... Solids, liquids and gases all expand when heat is added.
<u>How does heat affect the state of matter?
</u>
As temperatures increase, additional heat energy is applied to the constituent parts of a solid, which causes additional molecular motion. Molecules begin to push against one another and the overall volume of a substance increases. At this point, the matter has entered the liquid state.
