The melting point of moleculer hydrogen (H2) is ~14K (-259°C).  Draw a molecular level picture of what molecular hydrogen looks like below this temperature (i. e. as a solid). Why are the molecules of hydrogen sticking together?

i think a, hope it .

explanation:

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.

c. electrical charges of ionic bonds.
