Examples of plasma in the following topics:

  • Phases of Matter

    • There are four states of matter: solid, liquid, gas, and plasma.
    • Plasma is a gas that has been ionized.
    • Plasma contains ions and electrons that can move around freely.
    • Matter in the plasma state has variable volume and shape.
    • Plasma is the most common form of visible matter in the universe .

  • Blood Flow

    • Blood is the viscous fluid composed of plasma and cells.
    • The composition of the blood includes plasma, red blood cells, white blood cells and platelets.
    • Normal plasma behaves like a Newtonian fluid at rates of shear.
    • Typical values for the viscosity of normal human plasma at 37°C is 1.2Nsm-2.
    • The osmotic pressure of the plasma affects the mechanics of the circulation in several ways.

  • Characteristics of Sound

    • Sound is a longitudinal wave of pressure that travels through compressible medias, which can be solid, liquid, gaseous, or made of plasma.
    • Sound is a wave—a longitudinal wave of pressure that travels through compressible medias (i.e., solid, liquid, gaseous, or made of plasma).

  • What is a Fluid?

    • Fluids are a subset of the states of matter and include three of the four states—liquids, gases, and plasma (shown in ).
    • Four fundamental states of matter: 1) top left corner corresponds to solid; 2) top right corner corresponds to liquid; 3) bottom left corner corresponds to gas; 4) bottom right corner corresponds to plasma.

  • Problems

    • Let's say that you have a blackbody spectrum of temperature $T$ of photons passing through a region of hot plasma ($T_e$).You can assume that $T \ll T_e \ll m c^2/k$.
    • What is the brightness temperature of the photons in the Rayleigh-Jeans limit after passing through the plasma in terms of the Compton $y$-parameter?

  • B.5 Chapter 5

    • Consider a sphere of ionized hydrogen plasma that is undergoing spherical gravitational collapse.

  • Volume

    • Volume is the quantity of three-dimensional space contained by a closed boundary; it is the space that a substance (solid, liquid, gas or plasma) or shape occupies or contains.

  • LCDs

    • Unlike the newer cathode ray tube (CRT) and plasma displays, LCDS do not use phosphors.

  • Nuclear Fusion

    • Researchers are working on a reactor that theoretically will deliver 10 times more fusion energy than the amount needed to heat up plasma to required temperatures.

  • The Electron-Volt

    • In plasma physics, the electron volt can be used as a unit of temperature.
