A hydrogen atom is an atom of the chemical element hydrogen. The electrically neutral atom contains a single positively charged proton and a single negatively charged electron bound to the nucleus by the Coulomb force. Atomic hydrogen constitutes about 75% of the baryonic mass of the universe.

im guessing a natural resource? sorry thats the only answeri can think of
1670 km/h; 40 200 km/day
<em>a) Velocity in kilometers per hour</em>
The conversion factors are 1 km/1000 m, 60 s/1 min, and 60 min/1 h.
We can string these together to get
Velocity = (465 m/1 s) x (1 km/1000 m) x (60s/1min) x (60 min/1 h)
= 1674 km/h
= 1670 km/h (three significant figures)
<em>b) Velocity in kilometers per day
</em>
The conversion factor is 24 h/1 day.
Velocity = (1674 km/1 h) x (24 h/1 day) = 40 200 km/day
Answer:
See explanation
Explanation:
a) Every substance melts at a particular temperature known as the melting point of the substance. The melting point of ice is 0°C. Hence ice melts at 0°C.
b) There are three states of matter; solid liquid and gas. The particles of matter in each stage of matter possess varying degrees of freedom.
In the solid state, the intermolecular forces between the particles of water that compose ice are very strong. Hence the particles do not translate, they only vibrate or rotate about their mean positions.
In the liquid state, the magnitude of intermolecular interaction is less than that of the solids hence the molecules can translate but not with a high kinetic energy.
In the gaseous state, there is a minimum intermolecular interaction between particles theoretically hence the particles are really free to move about with a very high kinetic energy.
