Iced tea takes longer to warm up than a cold can of soft drink due to differences in thermal conductivity between glass and metal. The heat transfer rate is generally faster in metal, which can affect how quickly the beverage warms. Additionally, if the iced tea contains ice, it will require more time to reach room temperature as the ice absorbs heat. Conducting a test with actual measurements could provide clearer insights into the warming times of both beverages. Understanding these factors can clarify why iced tea may take longer to warm up compared to a cold soft drink.
