1 Which of the following is an example of decreasing thermal energy causing matter to change?
A A crayon melts in a hot car.
B A puddle evaporates on a hot day.
C Water becomes ice in the freezer.
D A marshmallow turns brown when heated.

C. Water becomes ice in the freezer

Explanation:

Thermal energy is basically heat, so decreasing thermal energy is decreasing heat, or something getting COLDER. In the other three examples, they are all getting WARMER.

the nitrogen cycle provides nitrogen to the ecosystem from the atmosphere, ground and oceans. nitrogen is an important component of complex molecules such as amino acids and nucleotides, which lead to the creation of proteins and dna, the building blocks of all life. plants absorb nitrogen in the form of ammonium, nitrate ion and, on rare occasions, as amino acids. animals receive nitrogen necessary for biological processes from feeding on living or dead organic matter.
