Matter and energy y in the environment
It has mass and takes up space
Matter
It has indefinite shape and indefinite volume
Gas
This change happens when sugar melts into caramel
Physical change
This method is use to separate homogeneous mixtures based on the melting point of the solid.
Evaporation
Have a positive charge and contains the 99.99% if the mass of the atom
Atomic nucleus
This kind of energy is produced by the plants through photosynthesis.

Chemical change
This methods separates pigments, amino acids, lipids, and vitamins
Chromatography
Determines the atomic number of elements
Protons
It is another way of calling the secondary consumers in the trophic chain
This state of matter is found when gases are cooled at near absolute zero temperatures.
Bose-Einstein condensate
Property that states "one gram of sand has 3x106 of sand grains"
Physical property
This method for separating heterogeneous mixtures is based on the density of the liquids or mass of the solids.
Decantation
