These observations highlight the relativity of temperature perception; sensory experiences are influenced by prior conditions. The same temperature can feel different based on what the body has previously experienced, demonstrating the adaptive nature of our sensory system.

During summer, tap water can become hotter due to prolonged exposure to ambient temperatures and heat from pipes. In contrast, water from a matka or refrigerator remains cooler, thanks to natural insulation or refrigeration.
I learned about temperature as a measure of heat, different scales like Celsius and Fahrenheit, and various measurement tools such as thermometers. Understanding these concepts is essential for conducting experiments and applying scientific principles in real life.
The temperature of ice is typically 0°C (32°F) when it melts, while boiling water reaches 100°C (212°F) at sea level. These temperatures represent key reference points in understanding thermal energy and phase changes.
Laboratory thermometers typically use mercury as the liquid, appreciated for its wide temperature range and consistent thermal expansion. However, some modern versions use colored alcohol, providing safer alternatives while maintaining accuracy in temperature measurement.
Body temperature varies due to several factors, including age—infants typically have higher temperatures—time of day, as it tends to be lower in the morning and higher in the evening, and activity level, affecting metabolic heat production.
