Silicon melt at 1410 degree celsius. phosphonus melt at 44 degree celsius. Explain the difference in these melting point by referring to forces between the particles and energy.

1.solid

2.carbon dioxide

3.helium

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
