but where Is the volume in order for us to determine the concentration. since we have moles in H+ ions
then you can say
concentration = M*1000/V
Pressure
Explanation:
Pressure is a measure of force per unit area.
Pressure is defined as the force exerted on a body across a unit area. The unit of pressure is N/m² or Pascal.
Pressure = 
The more the force acting on a body the more the pressure felt. A small surface area and a large force increases pressure on a body.
it is right to say that pressure is proportional to force but inversely proportional to area.

Alright, so a few seem almost self-explanatory.
"Energy from moving air" -> wind
"Energy in waves from the sun" -> solar.
But I digress.
The list goes (in order of the descriptions):
9 (Black rock...)
7 (Heat inside the Earth...)
8 (Flowing water...)
3 (Wood, waste, and garbage...)
2 (Moving air...)
4 (Splitting atoms...)
5 (Portable fossil fuel...)
1 (Used by cars...) petroleum is gasoline when refined
10 (Moved by pipeline...) This is true of petroleum too, but we don't burn natural gas in cars.
6 (Waves from the sun...)
