2. Place wax or a candle at one end of the metal as shown
in Figure 2(b).

3. Position a piece of stiff paper between the wax and wood.
This prevents direct heat from the stove from reaching the

wax as shown in Figure 2(c).

4. Place the charcoal stove at the other end of the metal
piece as shown in Figure 2(c).

5. Light the charcoal stove and wait. What happens to the

wax?

6. Write down what happened to the wax after lighting the

stove.

Results

After lighting the stove, the wax melted. This implies that, heat

was transferred from the source to the metal and wax.

Conclusion

This experiment proves that heat travels through solids by
conduction.
