When you walk barefoot on a concrete floor that has been in the sun, it feels very hot. Which mode of heat transfer causes your feet to feel hot?
Options
Option A
Convection
Option B
Radiation
Option C is correct
Conduction
Option D
Condensation
Explanation
Your feet feel hot because heat transfers directly from the hotter concrete to your cooler feet through direct physical contact. This mode of heat transfer is called conduction. Convection involves fluid movement, and radiation involves electromagnetic waves. Condensation is a phase change, not relevant here.
