State your hypothesis. if heat is added to a system during a phase change the temperature

This is an IF, THEN, BECAUSE statement. I'll put an example and then answer the question.

REMEMBER: I hypothesis is an educated guess

Example: IF carl spills juice on the carpet

               THEN his mother will punish him

               BECAUSE she's mad he spilled juice on the carpet  

IF heat is added to a system during a phase change

              THEN the temperature will raise

              BECAUSE you are adding heat

Hope this helps!

one would be wind another would be water density

igneous rocks are formed by solidification of cooled magma (molten rock), with or without crystallization, either below the surface as intrusive (plutonic) rocks or on the surface as extrusive (volcanic) rocks.  

the composition depends on the source magma. there are almost a thousand types of composition found till now.  

hope this
