A hot cup of coffee loses heat faster than a warm Why doesnt the reach room temperature before cup?

The specific heat capacity of a substance is the amount of heat required to raise the temperature of one gram of that substance by one degree Celsius. Different substances have different specific heat capacities. Water has a relatively high specific heat capacity, which means that it takes a lot of heat to raise the temperature of water. In contrast, metals have a relatively low specific heat capacity, which means that they heat up and cool down quickly.

How does this relate to coffee?

When you pour a cup of hot coffee, the coffee is at a higher temperature than the room. Heat will flow from the coffee to the room until the coffee reaches the same temperature as the room. The specific heat capacity of coffee is lower than the specific heat capacity of water, which means that it takes less heat to raise the temperature of coffee. As a result, the coffee will reach room temperature faster than a warm cup of water.

In addition, the surface area of a hot cup of coffee is usually larger than the surface area of a warm cup of water. This means that there is more surface area for heat to escape from the hot cup of coffee, which also causes it to cool down faster.
