A person trapped in a swamp is advised to lie down because as the area increases, the pressure decreases. Distributing the weight over a larger surface area reduces the pressure exerted on the swamp’s surface, making it less likely to ...

A heavy iceberg melts at the bottom rather than the top because the melting point decreases due to the pressure of the lower layer being higher. The increased pressure lowers the melting point, causing ice to melt more readily at ...
The ball keeps dancing in the water spray at intersections because due to higher velocity of water, pressure becomes higher. The increased velocity of water results in higher pressure, creating a force that propels the ball and causes it to ...
Skating on ice shows that on increasing the pressure, the melting point of ice decreases. The pressure applied by the skater’s weight lowers the melting point of the ice, causing it to briefly melt and form a thin layer of ...
The wall below the dam is made thick because the pressure of the fluid increases with increasing depth. This thick wall is necessary to withstand the increased pressure exerted by the water against it as the depth increases.
