A temperature difference of at least 20°C (36°F) is generally considered necessary for OTEC to be economically viable.

Multiple choice

What is the ideal temperature range for vermicomposting?

  1. 10-15°C

  2. 20-25°C

  3. 30-35°C

  4. 40-45°C

B Correct answer
Explanation

The optimal temperature range for vermicomposting is between 20-25°C (68-77°F). Temperatures outside this range can slow down the composting process or even harm the worms.

Multiple choice

What is the statistical definition of temperature?

  1. Temperature is proportional to the average kinetic energy of the particles in a system.

  2. Temperature is proportional to the total energy of the particles in a system.

  3. Temperature is proportional to the number of particles in a system.

  4. Temperature is proportional to the volume of a system.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Temperature is a measure of the average kinetic energy of the particles in a system. The higher the average kinetic energy, the higher the temperature.

Multiple choice

What is the temperature of a plasma sheath?

  1. Higher than in the bulk plasma

  2. Lower than in the bulk plasma

  3. Equal to the bulk plasma temperature

  4. Zero
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The temperature of a plasma sheath is typically higher than in the bulk plasma. This is because the electric field in the sheath accelerates ions towards the surface, which increases their kinetic energy and thus their temperature.

Multiple choice

What is the typical temperature range for optimal biogas production in anaerobic digestion systems?

  1. 0-10 °C

  2. 10-20 °C

  3. 20-30 °C

  4. 30-40 °C
