Question

A mass is performing vertical circular motion (see figure).If The average velocity of the particle is increased, then at which point the string will break :

Answer 1

The melting point and boiling point of hydrocarbons generally increases with the increase in molar mass. It is because, with the increase in molar mass, the molecule becomes larger and so the binding forces between those molecules that holds the particles very firmly together in solid or liquid phase, becomes stronger, and so it requires more energy to break these bonds and thus the melting and boiling points of the hydrocarbons increases.
