12 paź 2020 · The state of a substance depends on the balance between the kinetic energy of the individual particles (molecules or atoms) and the intermolecular forces. The kinetic energy keeps the molecules apart and moving around, and is a function of the temperature of the substance and the intermolecular forces try to draw the particles together.

- Topic H: Condensed States and Attractive Forces Between Particles
Condensed matter physics is the field of physics that deals with the macroscopic and microscopic physical properties of matter, especially the solid and liquid phases, that arise from electromagnetic forces between atoms and electrons.
In condensed matter physics, a Bose–Einstein condensate (BEC) is a state of matter that is typically formed when a gas of bosons at very low densities is cooled to temperatures very close to absolute zero, i.e., 0 K (−273.15 °C; −459.67 °F).
12 paź 2020 · Know the two factors that determine the physical state of matter. Know how average kinetic energy of the particles changes with temperature. Know the types and relative strengths of attractive forces between particles.
20 wrz 2024 · condensed-matter physics, discipline that treats the thermal, elastic, electrical, magnetic, and optical properties of solid and liquid substances. Condensed-matter physics grew at an explosive rate during the second half of the 20th century, and it has scored numerous important scientific and technical achievements, including the transistor .
12 paź 2020 · The state exhibited by a given sample of matter depends on the identity, temperature, and pressure of the sample. A phase diagram is a graphic summary of the physical state of a substance as a function of temperature and pressure in a closed system.
The density of states of an electron in a metal increases with energy, because there are more ways for an electron to fill a high-energy state than a low-energy state. Pauli’s exclusion principle states that only two electrons (spin up and spin down) can occupy the same energy level.
