A circular metal loop is heated at point O as shown in the figure below.
- In which direction would heat flow in the loop?
- In which order the pins at points P, Q and R fixed with the help of wax fall if points O, P, Q and R are equidistant from each other?
- The heat will flow in both the directions, i.e., from O to P and O to R.
- At first the pins at R and P will fall simultaneously followed by the pin at Q.
