Which is an example of a situation that is in equilibrium?A. The amount of air in a room increases quickly when the door is opened. B. The amount of money in a bank account never changes C. The amount of water in a cup decreases as it evaporates D. A flower slowly grows taller
Answer:B the amount of money in a bank account never changes.
B. The amount of money in a bank account never changes.
Equilibrium is achieved when the state of a reversible reaction of opposing forces cancel each other out. While in a state of equilibrium, the competing influences are balanced out. Imagine a cup with a hole in it being filled with water from a tap. The level of water in this cup would stay the same if the rate at which the water that flows inside is the same as the water that flows outside. Option B will be the correct answer because the amount of money going into the account is at the same rate of money coming out of the account.
