There was a woodcutter. Everyday in the morning he used to go to the forest to cut wood. In the evening he would sell the wood in the city. One day he went deep into the forest. It was a very cold winter. His fingers were becoming numb. Every now and then, the woodcutter would put down his axe and bring his hands close to his mouth. Then he would blow hard on them to warm them.

Answer:
The woodcutter blew his hands every now and then while cutting the wood with his axe in order to feel the warmth on his palm. Let's understand why:
Explanation:
1. Friction:
When the woodcutter cuts the wood with his axe, there is a lot of friction between the axe and the wood. Friction is a force that opposes the motion between two surfaces in contact. In this case, the friction generates heat due to the rubbing of the surfaces.
2. Effect of Heat:
As the woodcutter continues to cut the wood, the friction generates heat on the surface of the axe. This heat is transferred from the axe to the woodcutter's palm through conduction. The palm comes in contact with the heated axe, causing the woodcutter's hands to warm up.
3. Feeling Warmth:
By blowing on his hands, the woodcutter is actually trying to cool down his palms. The act of blowing helps to dissipate the heat from his hands. As the air from the woodcutter's breath comes in contact with his palms, it carries away some of the heat, thus providing a cooling effect.
4. Continuous Process:
The woodcutter blows his hands every now and then because the heat generated by the friction keeps accumulating on his palms. By blowing on his hands, he can prevent his hands from getting too hot and uncomfortable.
In conclusion, the woodcutter blows his hands while cutting wood with his axe to feel the warmth on his palms. This helps him cool down his hands and prevent them from getting too hot due to the heat generated by the friction between the axe and the wood.
