The use of flowing water to power a turbine to produce electrical energy
Answer:
Explanation:
We can use the Ideal Gas Law to calculate the density of the gas.
pV = nRT
n = m/M Substitute for n
pV = (m/M)RT Multiply both sides by M
pVM = mRT Divide both sides by V
pM = (m/V) RT
ρ = m/V Substitute for m/V
pM = ρRT Divide each side by RT
![\rho = \dfrac{pM }{RT}](https://tex.z-dn.net/?f=%5Crho%20%3D%20%5Cdfrac%7BpM%20%7D%7BRT%7D)
Data:
The gas is N₂ at STP (0 °C and 1 bar)
p = 1 bar
M = 28.01 g/mol
R = 0.083 14 bar·L·K⁻¹mol⁻¹
T = 0 °C = 273.15 K
ρ = (1 × 28.01)/(0.083 14 × 273.15) = 1.23 g/L
![\text{The density of the gas is $\large \boxed{\textbf{1.23 g/L}}$}](https://tex.z-dn.net/?f=%5Ctext%7BThe%20density%20of%20the%20gas%20is%20%24%5Clarge%20%5Cboxed%7B%5Ctextbf%7B1.23%20g%2FL%7D%7D%24%7D)
It appears that you are using the old definition of STP. Standard pressure has been defined as 1 bar since 1982.
Because when the seed lands it reproduces
Answer:
1. Agitating the solution
2. Adding Heat
Explanation:
Solubility of solute in solution can be enhanced by:
1 agitating the solution. To agitate simply means to stir continuously. When a solute is introduced into a solvent, continuous agitation (stirring) of the solution will facilitate the solubility of the solute in the solvent.
2. Adding heat. In this context, the addition of heat means to increase the temperature of the solvent as the solute are introduced. Solubility of solute is anhanced as heat is supplied to the solvent and also, the solubility decreases as heat is reduced.
