Ocean currents determine the various directions of wind movement.

<h3>What is ocean current?</h3>

Ocean currents are caused by differences in density as well as the temperature of the moving winds across the ocean. In the ocean, warm water is found at the top while cooler water occurs far below.

Warm ocean currents originate near the equator and move towards the poles. The ocean currents control the direction of winds in an area.

A certain gas is present in a 13.0 L cylinder at 1.0 atm pressure. If the pressure is increased to 2.0 atm , the volume of the g
Scorpion4ik [409]
<h3>Answer:</h3>

The gas obeys the Boyle's law

<h3>Explanation:</h3>
  • According to Boyle's law, the volume of a fixed mass of a gas and the pressure are inversely proportional at constant absolute temperature.
  • That is; P\alpha\frac{1}{V}
  • Therefore, k=PV, where k is a constant
  • At varying volume and pressures while keeping absolute temperature constant; k = P1V1 =P2V2

In this case, we are given;

Initial Volume of 13.0 L at initial pressure of 1.0 atm

New volume of 6.5 L at new pressure of 2.0 atm

But, K = PV

Therefore,

k1 = P1V1

   = 1.0 atm × 13.0 L

  = 13 atm.L

k2 = P2V2

    = 2.0 atm × 6.5 L

    = 13 atm.L

Thus, k1=k2

Thus, the gas obeys the Boyle's law

Write the pressure equilibrium constant expression for this reaction. 2CO2 (g) + 4H2O (g) → 2CH3OH (l) + 3O2 (g)
-BARSIC- [3]

Answer:

The pressure equilibrium constant (Kp) = (P O₂)³/(P CO₂)²(P H₂O)⁴.

Explanation:

  • For the reaction:

<em>2CO₂ (g) + 4H₂O (g) → 2CH₃OH (l) + 3O₂ (g).</em>

<em></em>

The pressure equilibrium constant (Kp) = the product of the pressure of the products side components / the product of the pressure of the reactantss side components.

each one is raised to a power equal to its coefficient.

<em>∴ The pressure equilibrium constant (Kp) = (P O₂)³/(P CO₂)²(P H₂O)⁴.</em>
