Thermal 1 & 2

    Cards (11)

    • Heat:
      energy transferred between 2 objects because of the temperature difference between them.
    • Thermal equilibrium:
      occurs when 2 objects are in thermal contact with each other and when they are at the same temperature, there is no net heat flow between them 2 objects.
    • Zeroth Law of Thermodynamics:
      If objects A and B are each in thermal equilibrium with a third object C, then A and B are in thermal equilibrium with each other.
    • Ideal Gas:
      is a gas which obeys the equation of state pV = nRT where p is the pressure of the gas, V is the volume of the gas, T is the thermodynamic temperature and n is the number of moles of the gas at all pressure, volume and temperature.
    • Mole:
      1 mole of a substance is the amount of substance that contains a number of particles equal to the Avogrado’s constant.
    • Heat Capacity:

      quantity of heat required to produce a unit temperature rise of the body without a change in phase of the body.
    • Specific Heat Capacity:
      quantity of heat required to produce a unit temperature rise of the body per unit mass without a change in phase of the body.
    • Specific Latent Heat of Fusion:
      quantity of heat required to convert a unit mass of solid to liquid without a change of temperature
    • Specific Latent Heat of Vaporization:
      quantity of heat required to convert a unit mass of liquid to gas without any change of temperature.
    • Internal Energy:
      internal energy of a system is determined by the state of the system. It can be expressed as the sum of the random distribution of microscopic kinetic energies and potential energies of all molecules of the system
    • First Law of Thermodynamics:
      states that in a closed system, the increase in the internal energy of a system is equal to the sum of the heat supplied to the system and the work done on the system. The internal energy of a system depends only on its state
