Calculate the wavelength of a photon that has emitted a photon with the energy of 6.38 x10^-24 J. 1.27 x10^-48 m
3.46 x10^-19 m
3.12 x10^-2 m
3.21 x10^1 m

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.

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.
