1. Why does a nail drown in water?
A nail does not have ample surface to displace water and reduce its weight. This is why a nail drowns when left in water.
2. Why does a boat float on water?
A boat floats on water because its surface area submerged in water is higher than its weight. It helps the boat to float. For the same reasons, a rolled puri drowns in oil but floats when it puffs up.
3. Why do people float in the Dead Sea?
The Dead Sea is known for its high content of salt. It is so salty that it does not have fish in it. Due to the heaviness of the water, people float.
