As the vibration of molecules increases, the of the substance increases. temperature internal energy kinetic energy all of the above

Answer

When vibration of molecules increases, the temperature, internal energy and kinetic energy of the substance increases.

Explanations

The kinetic theory of matter explains that when vibration of molecules increase as a result of heat, molecules move faster and the space between atoms increases. The increased molecular motion results into expansion of the object which takes more space. Increased vibration can make a molecule absorb discrete amounts of energy through the various vibration modes. When the motion increases, the velocity of the entire molecule rises as a random Brownian movement to increase the kinetic energy and internal energy of the molecule.

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
