A circular metal loop is heated at point O as shown in Figure 4.6. Fig. 4.6

(i) In which direction would heat flow in the loop?

(ii) 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?

(i) Heat flows in solid in all direction, with the same speed so heat will flow from O to P and also from O to R.

(ii) First heat travels to R and P so the pin R and P will fall first then the heat goes to point Q so now the pin Q will fall down.
