The sidewalk then radiates this heat back into the environment, contributing to urban heat island effect.
When the temperature is 114 F how hot is a concrete sidewalk?
A concrete sidewalk can absorb and retain heat, so it can be significantly hotter than the air temperature. On a 114°F day, a concrete sidewalk can easily reach temperatures of 130-150°F or even higher, depending on factors like sunlight exposure and time of day. This can cause it to be quite uncomfortable to walk on without proper protection for your feet.
Why does a person move forward when he or she pushes on the sidewalk?
