5.2.12.A. Properties of Matter: All objects and substances in the natural world are composed of matter. Matter has two fundamental properties: matter takes up space, and matter has inertia.
Differences in the physical properties of solids, liquids, and gases are explained by the ways in which the atoms, ions, or molecules of the substances are arranged, and by the strength of the forces of attraction between the atoms, ions, or molecules.
5.2.12.A.2. Account for the differences in the physical properties of solids, liquids, and gases.
Electrons, protons, and neutrons are parts of the atom and have measurable properties, including mass and, in the case of protons and electrons, charge. The nuclei of atoms are composed of protons and neutrons. A kind of force that is only evident at nuclear distances holds the particles of the nucleus together against the electrical repulsion between the protons.

Gas particles move independently and are far apart relative to each other. The behavior of gases can be explained by the kinetic molecular theory. The kinetic molecular theory can be used to explain the relationship between pressure and volume, volume and temperature, pressure and temperature, and the number of particles in a gas sample. There is a natural tendency for a system to move in the direction of disorder or entropy.
5.2.12.C.1. Use the kinetic molecular theory to describe and explain the properties of solids, liquids, and gases.
Heating increases the energy of the atoms composing elements and the molecules or ions composing compounds. As the kinetic energy of the atoms, molecules, or ions increases, the temperature of the matter increases. Heating a pure solid increases the vibrational energy of its atoms, molecules, or ions. When the vibrational energy of the molecules of a pure substance becomes great enough, the solid melts.
5.2.12.C.2. Account for any trends in the melting points and boiling points of various compounds.

Earth’s radiation budget varies globally, but is balanced. Earth’s hydrologic cycle is complex and varies globally, regionally, and locally.
5.4.12.F.3. Explain variations in the global energy budget and hydrologic cycle at the local, regional, and global scales.
Global climate differences result from the uneven heating of Earth’s surface by the Sun. Seasonal climate variations are due to the tilt of Earth’s axis with respect to the plane of Earth’s nearly circular orbit around the Sun.
5.4.12.F.1. Explain that it is warmer in summer and colder in winter for people in New Jersey because the intensity of sunlight is greater and the days are longer in summer than in winter. Connect these seasonal changes in sunlight to the tilt of Earth's axis with respect to the plane of its orbit around the Sun.
