Questions and Answers

What is the temperature range of the thermosphere?

  • 2500 to 3000 degrees Celsius
  • 0 to 2500 degrees Celsius (correct)
  • 80 to 700 degrees Celsius
  • 80 to 7000 degrees Celsius

Why does the thermosphere have a very low thermal energy despite its high temperature?

  • Due to the low kinetic energy of gas molecules
  • The temperature is not actually high
  • Because it contains very few gas molecules (correct)
  • The molecules are closely packed together

What is the primary difference between temperature and thermal energy?

  • Temperature is the transfer of thermal energy, while thermal energy is the average kinetic energy
  • Temperature is the total kinetic energy, while thermal energy is the average kinetic energy
  • Temperature is the average kinetic energy, while thermal energy is total kinetic energy (correct)
  • Temperature and thermal energy are the same thing
