Consider each of the following systems for long times, at which their behacioor is time invariant. Identify each system as equilibrium or steady state.

1) A hose supplies water at a constant rate to a bucket with a hole in it. A constant water level is maintained

2)A mixture of reacting gas molecules is constrained to a fixed temperature, e.g., H2, O2 and H2O at 600 K.

3) Ice floats in water, thermally insulated from its surroundings.

4) Molten steel is poured into a continuous casting mill while withdrawing solid steel from the bottom.

(5) A foil birthday balloon is brought into a hot room.

Solutions

Expert Solution

In the case of a system attains steady state, then the recently observed behavior of the system will continue into the future.

In the case of the rate of forward and backward reactions is equal, then the reaction is said to be at equilibrium.

hink about the following game: A fair coin is tossed 10 times. Each time the toss results in heads, you receive $10; for tails, you get nothing. What is the maximum amount you would pay to play the game? Define a success as a toss that lands on heads. Then the probability of a success is 0.5, and the expected number of successes after 10 tosses is 10(0.5) = 5. Since each success pays $10, the total amount you would...
