How does temp affect the phase of a substance
notka56 [123]

Answer:

state of matter

Explanation:

so take water for example, water has a melting point and a boiling point right? So if it's below 0 degrees, then it's in its solid phase. If the temperature is above 0 degrees, then the water starts to melt into its liquid phase. Then when the temperature is above 100 degrees, water starts to boil and become its gas phase. This is the same for all substances. The only difference is different substances have different melting and boiling points so the numbers will be different depending on your substance. hope this helped!

givi [52]

Answer:

SiO2(s) + 3C(s)  ------> SiC(s) + 2CO(g)

Explanation:

The formula for silicon oxide is SiO2 and carbon is C. silicon carbide is SiC

and carbon monoxide is CO.

An arrow is always used to separate the reactants (left) and products (right).

A balanced equation must contain equal number of atoms in each side of the equation.

For example in the equation above, there are 1 atom of silicon appears on each side; 2 atoms of oxygen and three atoms of carbon.
