Which of these best explains why a paper clip can float on water? a)water has a very high specific heat.
b)water molecules at the surface experience fewer hydrogen bonds than water molecules within the liquid.
c)the metal in the paper clip has a lower mass than the water.
d)water molecules near the surface produce more buoyant force than water molecules within the liquid.

The answer is d. water molecules near the surface produce more buoyant force than water molecules within the liquid

Explanation: Surface tension is defined as the attraction on the water of like particles to one another. Water molecules on a surface undergoes cohesion or the sticking together of one molecule to another of the same material.

D)Water molecules near the surface produce more buoyant force than water molecules within the liquid.

Explanation:

Buoyant force that is provided by water molecules such that the object can float on the surface of the water. According to Archimedes principle for flotation to occur the buoyant force must be equal to the weight of the object.  If the buoyant force is less than the weight of the object, then the object will sink.

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.
