  • Q11
    Which of the following describes a system in thermal equilibrium?
    A hot object and a cold object are in contact with each other.
    An object is heating up due to a nearby fireplace.
    Two objects of exactly the same temperature are in contact with each other - heat can transfer freely between them, but no heat transfer is happening.
    Two objects of exactly the same temperature have an impenetrable heat barrier between them.

  • Q12
    By what mechanism do two objects of different temperatures reach thermal equilibrium?
    Heat spontaneously transfers from one place to another, regardless of temperature.
    None of the answers are correct; the objects never reach thermal equilibrium.
    Faster moving molecules in the hotter object hit the slower moving molecules in the colder object, until the heat has fully equalized.
    Faster moving molecules in the colder object hit the slower moving molecules in the hotter object, until heat has fully equalized.
