This quiz contains 5 open-ended questions related to thermal physics. Read each question carefully and provide your answer as concisely as possible.


  1. What is thermal conductivity and why is it important?
  2. How is temperature related to thermal energy?
  3. Explain the difference between conduction, convection, and radiation in terms of heat transfer.
  4. What is specific heat capacity and how can it be calculated?
  5. How does thermal expansion occur and what effect does it have on materials?


  1. Thermal conductivity is the measure of a material’s ability to conduct heat. It is an important characteristic to consider when selecting materials for constructing thermal systems, as materials with higher thermal conductivity can transfer heat more efficiently.

  2. Temperature is a measure of the average kinetic energy of molecules in a substance, while thermal energy is the total kinetic and potential energy of all the molecules in a substance. As temperature increases, so does the thermal energy of the substance.

  3. Conduction is the transfer of heat through direct contact between two objects, convection is the transfer of heat through the movement of fluids, and radiation is the transfer of heat through electromagnetic waves.

  4. Specific heat capacity is the amount of heat required to raise the temperature of 1 gram of a substance by 1 degree Celsius. It can be calculated by dividing the amount of heat absorbed or released by the mass of the substance and the temperature change.

  5. Thermal expansion occurs when the temperature of a material increases, causing its particles to vibrate and move apart, leading to an increase in volume. The degree of expansion depends on the material’s coefficient of thermal expansion, which varies for different materials. The effect of thermal expansion can be problematic in many systems and structures, as it can result in distortion, warping, and even breakage.
