If the relationship between price and quantity demanded is similar to the relationship between temperature and the rate of ice melting, what would be the best analogy for the relationship between price and quantity supplied?

The relationship between price and quantity supplied can be compared to the relationship between heat and the rate at which a pot of water boils. Just as increasing the heat makes the water boil faster, raising the price encourages producers to supply more of a product. When prices go up, businesses see the chance to make more profit, so they are willing to produce and sell more. For example, if a bakery can sell bread for a higher price, it will likely bake more loaves to meet that demand. This shows how both higher prices and higher heat lead to increased activity in their respective processes.
