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.
Approximately 1/10 part of an iceberg floating in the sea remains above the surface of the sea. This is due to the difference in densities between ice and seawater, where the density of ice is about 90% that of seawater, ...
The reason for the floating of clouds in the atmosphere is density. Clouds consist of tiny water droplets or ice crystals that are less dense than the surrounding air. This lower density causes the clouds to float or remain suspended ...
A swimmer finds it easier to swim in seawater than in a river because the density of seawater is higher than that of ordinary water. The higher density provides more buoyant force, which helps the swimmer to float and swim ...
