Liquid gold is poured into molds and cools to become solid bars. The gold is "FREEZING"

Liquid nitrogen becomes a gas when it is poured out of its container. The nitrogen is "BOILING"

Solid iron is heated to high temperatures so that it becomes a liquid. The iron is "MELTING"

Water vapor in the air becomes tiny liquid droplets that form fog. The water is "CONDENSING'

In a very cold cryogenic freezer, solid oxygen forms on the walls from the oxygen gas in the air. The oxygen is "DEPOSITING"

In the high desert, snow changes to water vapor without becoming liquid water. The snow is "SUBLIMING"

The gold is frozen. The nitrogen is vaporized. The iron is melted. The water is condensed. The oxygen is deposited. The snow is sublimed.

Phase changes are physical changes, in which matter changes from one state to another. Each phase change has its own name.

Let's identify each of the phase changes described below.

The gold is frozen. The nitrogen is vaporized. The iron is melted. The water is condensed. The oxygen is deposited. The snow is sublimed.

why is cellular respiration important for homeostasis?

it changes food into energy that the organism can use.

which of the following is most likely to happen if a cell is not able to divide?

the cell will not be replaced when it is damaged.

explanation:

answer is: nuclear fusion produces elements that are heavier than helium.

nuclei combine to form a heavier nucleus, releasing energy.  

for example, fusion of hydrogen atoms at the sun.  

this fusion nuclear reaction is in the inner core of the sun and hydrogen (atomic number 1) is conveted into helium (atomic number 2).  

the inner core is the central region of the sun and all solar energy is produced in the core by nuclear fusion.
