Question

2. Talcum powder gives a cooling sensation. Explain this by using the concept of interconversion of states

This cooling effect is due to dry nature of talcum powder. As we apply this powder to our body, they absorb the sweat and that causes evaporation of sweat overall. Evaporation is an endothermic process so it reduces the temperature of body and overall we feel cooling effect.
