  • Thermodynamics
    Thermodynamics is a branch of physics concerned with heat and temperature and their relation to energy and work.
  • Calorie
    A calorie is a unit of energy
  • Closed-system
    A physical system that doesn't exchange any matter with its surroundings, and isn't subject to any force whose source is external to the system.
  • Conduction
    Conduction is the transfer of heat by microscopic collisions of particles and movement of electrons within a body.
  • Convection
    Convection is the heat transfer due to bulk movement of molecules within fluids such as gases and liquids, including molten rock.
  • Fahrenheit
    The Fahrenheit scale is a temperature scale based on one proposed in 1724 by Amsterdam-based physicist Daniel Gabriel Fahrenheit, after whom the scale is named.
  • Gas
    an airlike fluid substance which expands freely to fill any space available, irrespective of its quantity.
  • Heat
    the quality of being hot; high temperature.
  • Insulator
    a thing or substance used for insulation, in particular.
  • Kelvin
    The absolute thermodynamic temperature scale using as its null point absolute zero, the temperature at which all thermal motion ceases in the classical description of thermodynamics.
  • Kinetic Energy
    Energy that a body possesses by virtue of being in motion.
  • Latent Heat
    The heat required to convert a solid into a liquid or vapor, or a liquid into a vapor, without change of temperature.
  • Liquid
    A nearly incompressible fluid that conforms to the shape of its container but retains a constant volume independent of pressure.
  • Open-system
    A system that freely exchanges energy and matter with its surroundings
  • Phase Change
    When a substance absorbs heat without an increase in temperature by changing from one physical state (or phase) to another, as from a solid to a liquid (melting), from a solid to a vapour (sublimation), from a liquid to a vapour (boiling), or from one solid form to another (usually called a crystalline.
  • Potential Energy
    The energy possessed by an object because of its position relative to other objects, stresses within itself, its electric charge, or other factors.
  • Radiation
    The emission or transmission of energy in the form of waves or particles through space or through a material medium.
  • Solid
    firm and stable in shape.
  • Specific Heat
    The amount of heat per unit mass required to raise the temperature by one degree Celsius.
  • Temperature
    the degree or intensity of heat present in a substance or object, especially as expressed according to a comparative scale and shown by a thermometer or perceived by touch.
  • Thermal Energy
    The internal energy present in a system due to its temperature.
  • Thermal Equilibrium
    Two physical systems are in thermal equilibrium if no heat flows between them when they are connected by a path permeable to heat.
