In the simple Keynesian portion of the upward sloping short-run aggregate supply curve O equilibrium real GDP is determined by both aggregate supply and aggregate demand. O equilibrium real GDP is supply-determined O equilibrium real GDP is neither determined by aggregate supply nor by aggregate demand. O equilibrium real GDP is demand-determined

Answers

Aggregate supply is the total quantity of output firms will produce and sell—in other words, the real GDP.

Why is the Keynesian aggregate supply curve upward sloping?

Given that wages and prices are less flexible in the short run, the Keynesian model demonstrates that the aggregate supply curve is upward sloping. This approach makes it more probable that the economy will not reach full employment, allowing businesses to expand their workforce and boost output without having to raise prices or pay.

The economy will be in balance when the aggregate expenditure line reaches the 45-degree line. It is the only location along the aggregate expenditure line where total spending on aggregate demand and total production are equal.

The quantity of finished goods and services delivered overall at various price points is represented by the aggregate supply (AS) curve. Because wages and other costs are sticky in the short term, it slopes upward.

Explanation:

How many Liters are 5.1 grams of Cl2?

Answers

5.1 grams of Cl2 is calculated as 1.610 L.  As all the gases that behave ideally have the same number density, they will also have the same molar volume.

What is molar volume?

Molar volume of a substance is the volume occupied by one mole of  substance at given temperature and pressure. It is equal to the molecular mass of the substance divided by its density at the given temperature and pressure: It has SI unit of cubic meters per mole.

Given 5.1 grams of Cl2

As molar mass of Cl2 = 70.906 g/mol

So, moles = 5.1/70.906

= 0.0719 mol

Volume= moles of cl2 * molar volume of cl2

As molar volume of cl2 = 22.40 L

So, Volume = 0.0719 * 22.40

Volume = 1.610 L

Molecular size and shape: Larger or non-spherical molecules tend to deviate from ideal behavior more in extreme conditions.

Phase transitions: As the temperature and pressure of a gas are increased or decreased, the gas may undergo a phase transition (such as condensation or liquefaction) that changes its behavior.

Kinetic energy: At high temperatures, the kinetic energy of the gas molecules increases, leading to deviations from ideal behavior.
