Explain why, some white patches are formed on our clothes during summer, especially in areas like underarams.

Explanation

**Step-by-Step Solution:**

1. **Understanding Sweating**: During the summer, the temperature rises significantly, causing our bodies to heat up. To maintain a stable internal temperature, our bodies activate a cooling mechanism known as sweating.

2. **Composition of Sweat**: Sweat is primarily composed of water and salts (such as sodium chloride). When we sweat, these substances are released from our sweat glands onto the surface of our skin.

3. **Evaporation Process**: As the sweat forms on our skin, the water component begins to evaporate due to the heat in the environment. This evaporation process helps cool down the body.
