SUMMARY

Objects feel different temperatures due to the interaction between their thermal properties and human heat receptors. When an object has a temperature higher than skin temperature, it transfers heat to the skin through conduction, resulting in a sensation of warmth or heat. Conversely, if an object is below skin temperature, it absorbs heat from the skin, creating a sensation of cold. This fundamental understanding of thermal conduction is essential for grasping how temperature perception works.

PREREQUISITES
  • Understanding of thermal conduction principles
  • Basic knowledge of human physiology, specifically heat receptors
  • Familiarity with temperature measurement concepts
  • Awareness of material properties affecting heat transfer
NEXT STEPS
  • Research the role of heat receptors in temperature perception
  • Explore the physics of thermal conduction in different materials
  • Investigate the impact of skin temperature on heat transfer
  • Learn about the mechanisms of heat absorption and transfer in various environments
USEFUL FOR

Students of physics, healthcare professionals, and anyone interested in the science of temperature perception and thermal dynamics.

Why exactly do things feel cold and hot?

Because we have heat receptors.
 
Good answer, Aixm. I'm going to elaborate upon it a bit, though. Something feels warm or even hot if its temperature is higher than that of your skin. In that situation, it transfers heat to you through conduction. If it feels cold, that's because it's below your skin temperature and is absorbing heat from you.
It's a lot more complicated than that, but the basis is correct.
