they are both types of passive transport which means they require no energy. They both work with the concentration gradient which means they go from a high concentration area to a low concentration area. The differences are simple diffusion just goes though the membrane of a cell while facilitated diffusion uses a protein channel
Simple diffusion: it is the process where molecules move from a area of high concentration to an are of lower concentration. There is no energy needed in simple diffusion. For example when sodium is highly concentration in a cell, it moves outside of the cell where sodium is less concentration. it takes no energy as simple diffusion is random and molecules move according to their concentration.

Answer:
Pressure = 4.81atm
Explanation:
Pressure = ?
Temperature = 20°C = (20 + 273.15)K = 293.15K
Volume = 2.50L
R = 0.082J/mol.K
n = 0.5mol
From ideal gas equation,
PV = nRT
P = pressure of the ideal gas
V = volume the gas occupies
n = number of moles of the gas
R = ideal gas constant and may varies due to unit of pressure and volume
T = temperature of the ideal gas
PV = nRT
Solve for P,
P = nRT/ V
P = (0.5 * 0.082 * 293.15) / 2.50
P = 12.01915 / 2.50
P = 4.807atm
P = 4.81atm
The pressure of the ideal gas is 4.81atm
Since the reaction gives off heat energy it is considered to be an exothermic reaction
The majority of wind turbines consist of three blades mounted to a tower made from tubular steel. There are less common varieties with two blades, or with concrete or steel lattice towers. At 100 feet or more above the ground, the tower allows the turbine to take advantage of faster wind speeds found at higher altitudes.
Turbines catch the wind's energy with their propeller-like blades, which act much like an airplane wing. When the wind blows, a pocket of low-pressure air forms on one side of the blade. The low-pressure air pocket then pulls the blade toward it, causing the rotor to turn. This is called lift. The force of the lift is much stronger than the wind's force against the front side of the blade, which is called drag. The combination of lift and drag causes the rotor to spin like a propeller. So therefore your answer would be A.
