Now imagine that you're waiting for your soup to cool down, and you leave it on the counter while you go do your homework. Your
homework is so interesting that you forget all about your soup, and now it's cold! Actually, if you were to measure the temperature, you'd find that your soup is the same temperature as the air in the room. What's going on?
Generally, heat flows from a hot environment to a cold (lesser temperature) environment. In this case, the soup is the hot environment and the air is the cold temperature.
Heat would continue to flow from one environment to another until thermal equilibrium is reached. At this thermal equilibrium, both environments would have the same temperature.
