Why does a sidewalk have built in cracks every few feet?
It is because if it was one big piece, the concrete would buckle and break just like bridges.
Sidewalks are built with cracks because in the summer something occurswhat is it?
they r called contraction joints. then every few of those then expansion joint. concrete is going to crack, so make it crack so it can't be seen,under the man made ones. concrete tends to crack symmetrically. so if ur sidewalk is 3 feet wide the contraction joints will be every 3 feet. then expansion joint, 3/4 inch with expansive material, every 4th one.

When you walk bearfoot across a hot sidewalk you feel heat on your feet. explain What is happening with the molecules in both the sidewalk and your feet and in which direction thermal energy is moving?
As you walk barefoot on a hot sidewalk, the sidewalk molecules vibrate more due to the heat, transferring thermal energy to your feet. The heat is moving from the sidewalk (higher temperature) to your feet (lower temperature), causing your feet to feel hot. The increased molecular vibrations in the sidewalk result in the sensation of heat on your feet as thermal energy is transferred.
