Toy balloons are filled with hydrogen gas, at standard temperature, from a 10.0-liter cylinder. the initial pressure of the gas
madam [21]
To answer this item, we are to assume that the given gas behaves ideally such that it can follow one of the simplified ideal gas law as written below,

                  P₁V₁ = P₂V₂

where P is the pressure and V is the volume. 

Substituting the known values, while V₂ is unknown,

                 (100 atm)(10 L) = (1 atm)(V₂)

The value of V₂ is calculated to be equal to 1000 L. 

The number of balloons that can be filled is as calculated.
                      n = (1000 L) / (1 L / balloon)
                               n = 1000

Four modes of sediment transport are:
netineya [11]
Here is 5


Dissolved Load - elements dissolved in solution

Suspended Load - very fine grained sediment such as clay and silt carried in suspension. The size grains that can be carried in suspension are dependent on the current velocity

Wash Load - a subset of the suspension load, extremely small particles (clay) that will remain in suspension independent of turbulence in the river

Saltation Load - particles that are temporarily carried in suspension but move by bouncing along the bottom
 
<span>Bed Load - sediment that moves by rolling or sliding along the bottom. These are generally the coarser grained sediments such as sand and gravel.</span>
