Knowing each state's population would help.
However New York, Washington state & Indiana are fairly populated with big cities.
Wyoming has the least population of the four states.
Nation states are difficult to create because of colonies ((tell me if u need to know why because I can help with that))
Convection occurs in fluids (so both liquids and gases, as well as rheids) and is the concerted, collective movement of groups or aggregates of molecules within the above through advection or diffusion or both at the same time. Convection can never take place in solids and is only specific to fluids.
