Which of the following is the best example of heat transferring from one source to another?

  1. Taking a cold shower

  2. Taking a hot bath

  3. Drinking iced tea

  4. Boiling water

The correct answer is: Taking a hot bath

Taking a hot bath is the best example of heat transferring from one source to another because in this scenario, the heat from the water is transferred to your body. When you immerse yourself in hot water, the temperature of the water is higher than that of your skin, leading to the transfer of thermal energy. This process is a clear demonstration of conduction, where heat moves from a warmer object (the water) to a cooler one (your body) until thermal equilibrium is reached. In contrast, while taking a cold shower, drinking iced tea, or boiling water involve temperature changes, they do not highlight the concept of heat transfer as effectively. A cold shower involves your body losing heat to the cold water, which is a different dynamic. Drinking iced tea doesn't involve heat transfer towards the body in a notable way, and boiling water primarily focuses on the process of heating water rather than transferring heat to another body.
