Questions and Answers

According to the 1st law of thermodynamics, what happens when a cup of hot coffee is left in a cooler room?

  • The coffee gets even hotter due to heat transfer from the room air.
  • The amount of energy lost by the coffee is less than the amount gained by the surrounding air.
  • The coffee loses energy without affecting the surrounding air.
  • The amount of energy lost by the coffee is equal to the amount gained by the surrounding air. (correct)

    • What does the 1st law of thermodynamics not restrict?

  • The direction of a process (correct)
  • The speed of a process
  • The amount of energy in a process
  • The temperature change in a process

    • What is the limitation of the 1st law of thermodynamics?

  • It restricts the transfer of energy between different substances.
  • It does not ensure that a process can actually occur. (correct)
  • It only applies to closed systems.
  • It is only concerned with the quantity of energy.

    • Why does the process of hot coffee getting even hotter in a cooler room not occur?
