WebMar 10, 2024 · Paper clips float on the surface area of the water because of surface tension. Surface tension is the tendency of liquid molecules to attract each other due to cohesive forces. In floating paper clip science experiment, the water molecules on the surface area attract each other and stay tight due to cohesive force. The equation to calculate the pressure inside a fluid in equilibrium is: where f is the force density exerted by some outer field on the fluid, and σ is the Cauchy stress tensor. In this case the stress tensor is proportional to the identity tensor: Here δij is the Kronecker delta. Using this the above equation becomes:

WebJul 19, 2024 · They float because water molecules hold on to one another in a way that creates surface tension. This property allows many things to float on water, including your rubber band and pin. WebSo if you put the needle gently without breaking the surface tension, the water surface will slightly curve downward and due to elasticity it would cancel out the downward force of needle & therefore the needle will float. Did i get it right? Now I do not get the relation between these two parts. lamani dance
