  1. 1The zeroth law: If two systems are in [blank_start]thermalequilibrium[blank_end] with a [blank_start]third system[blank_end], they are also in
    thermal equilibrium with [blank_start]each other[blank_end].
    1. Athermal equilibrium
    2. Bthird system
    3. Ceach other
  2. 2The first law : It states that energy can be [blank_start]transformed[blank_end], i.e.
    changed from one form to another, but cannot be
    [blank_start]created or destroyed.[blank_end] It is usually formulated by
    stating that the change in the [blank_start]internal energy[blank_end] of a
    system ([blank_start]U[blank_end]) is equal to the amount of [blank_start]heatsupplied[blank_end] to the system ([blank_start]Q[blank_end]), minus the amount of
    [blank_start]work performed[blank_end] by the system on its
    surroundings ([blank_start]W[blank_end]).
    1. Atransformed
    2. Bcreated or destroyed.
    3. Cinternal energy
    4. DU
    5. Eheat supplied
    6. FQ
    7. Gwork performed
    8. HW
  3. 3What is the Mean Free Path and what do the symboles in its equation stand for?Image for question 3
    1. AThe mean distance that a particle travels before colliding with
      another particle is called the Mean Free Path of the fluid.

      l – mean free path, kB – Boltzman constant, T – temperature, d - atomic
      (molecular) diameter, p – pressure
    2. BThe spacing being particles within a substance is called the Mean Free Path of the fluid.

      l – mean free path, kB – Boltzman constant, T – temperature, d - atomic
      (molecular) diameter, p – pressure
    3. CThe mean distance that a particle travels before colliding with
      another particle is called the Mean Free Path of the fluid.

      l – mean free path, kB – Spring constant, T – temperature, d - atomic
      (molecular) diameter, p – pressure
  4. 4What do each of the symbols in this equation stand for.Image for question 4
    1. Aconductivity
    2. Bparticles per volume
    3. Cmean particle speed
    4. Dmean free path
    5. Emolar heat capacity
    6. FAvogadro’s number
  5. 5What is the thermal equivalent of the following equation: V = IR
    1. AdeltaT = Cp * R
    2. BT = q * R
    3. CdeltaT = q * R
    4. DP = q * Cp
  6. 6What is the equation below and label it?Image for question 6
    1. ATemperature
    2. Bthickness
    3. Cconductivity
    4. DThermal Resistance
    5. Esurface area
  7. 7Label the equation below and what does it find?Image for question 7
    1. Aheat transfer coefficient
    2. BVolume
    3. CSurface Area
    4. Dthermal conductivity
    5. EBiot Number
  8. 8When the [blank_start]thermal resistance[blank_end] to heat transferred into the object is
    [blank_start]larger[blank_end] than the resistance to heat being [blank_start]diffused[blank_end] completely within the
    object, the Biot number is less than 1.
    1. Athermal resistance
    2. Blarger
    3. Cdiffused
  9. 9Label the following equation for the capacitive model.Image for question 9
    1. ATemperature of fluid
    2. BInitial Temperature
    3. CTemperature after time
    4. Dheat capacity
    5. EHeat transfer co-effecient
    6. FTime
