Question

Imagine this experiment: Fill two buckets with water, one relatively cold and one hot. Fill a third bucket with water of an intermediate, lukewarm temperature. Put your left hand into the hot water, your tight had into the cold and wait one minute. Now quickly plunge both hands into the lukewarm water. Try to predict what sensations of temperature you will feel in each hand. Will they feel the same? Why?

Answer 1

Placing hands that have been in varying temperatures into lukewarm water results in different sensations due to our nerves' relative perception of temperature.

The right hand feels the water as cool while the left hand feels it as warm, demonstrating temperature perception's relativity.

Step-by-step explanation:

When you place your right hand in hot water and your left hand in cold water, then immediately afterwards place them both into lukewarm water, you'll experience different sensations in each hand. The right hand, which was in hot water, will find the lukewarm water cool, while the left hand, which was in cold water, will perceive the lukewarm water as warm.

This difference in sensation occurs because our nervous system judges temperature relative to its current condition. The temperature difference is what causes the perception of hotness or coolness to change. It's not the water itself that possesses the sensation of temperature, but rather our body's response to it.

Temperature perception is a relative concept, based on how the nervous system reacts to various stimuli. The scientific definition of temperature is measured by a thermometer and is not influenced by human sensations. The lukewarm water triggers a different response in each hand due to the temperature adaptation of the nerves in your skin.
