Thermohaline currents are influenced by wind. True or false?

Chemistry
1 answer:
tresset_1 [31]3 years ago
6 0

Answer:

FALSE

Explanation:

The under-water deep ocean currents that are generated due to the differences in the water density are generally termed as the thermohaline circulation. It is mainly controlled by the two factors namely the temperature and the salinity. The word 'thermohaline' is directly derived from the temperature (thermo) and salinity (haline).

This thermohaline circulation is considered as the oceanic conveyor belt that allows the water to move under the surface of water at certain depths from the equator to the poles and back from the poles to the equator.

Thus, it is directly associated with the density of the water. It has no relation with the wind.

Hence, the above statement is False.

The density of magnesium is 1.7 g/cm3, and the density of iron is 7.9 g/cm3. Consider a block of iron with a mass of 819 g. What
BigorU [14]

Answer:

mass of Mg=0.016g

Explanation:

P(Mg)=1.7g/cm³

P(Fe)=7.9g/cm³

m(Fe)=819g

P(Fe)=m(Fe)/v(Fe)

7.9=819/v(Fe)

v(Fe)=0.0096cm³

since v(Mg)=v(Fe)

=0.0096cm³

P(Mg)=m(Mg) /v(Mg)

1.7=m(Mg)/0.0096

m(Mg) = 0.016g

According to kinetic molecular theory, which of the following would not be considered an ideal gas
RideAnS [48]

Answer:

A gas at very low volumes, when gas particles are very close together

A gas at very low temperatures, when gas particles have very little kinetic energy

A gas with highly polar molecules that have very strong inter-molecular forces

Explanation:

The Kinetic Molecular Theory:

  • particles in a gas are in constant, random motion
  • combined volume of the particles is negligible
  • particles exert no forces on one another
  • any collisions between the particles are completely elastic
  • average kinetic energy of the particles is proportional to the temperature in kelvins

RM / NV / NF / EC / ET

Although none of the assumptions provided in the molecular theory of gases are strictly correct, they are fair enough for modeling some systems. It is an idealized approach of real systems. The fundamental presumptions are nearly identical to those of an ideal gas.

The most logical of the hypotheses is that of elastic collisions. Since gas molecules are treated as perfectly hard spheres in Newton's equations and elastic collisions, there is no energy lost in compressing the gas molecules during a collision.

For bulk, light gases at moderate temperatures and low to moderate pressures, it is acceptable to assume that there is an attractive force between the gas and the container wall. Since the walls of the containers only account for a minor portion of collisions in macroscopic quantities, they can typically be disregarded. Only until the gas's total density exceeds the kinetic energy do forces between its particles start to become significant. For light gases like He and straightforward diatomic gases, the kinetic energy of the gas molecules far outweighs the intramolecular interactions at normal temperatures.

But in a complete way of the KM theory being described:

The microscopic characteristics of atoms (or molecules) and their interactions, which result in observable macroscopic qualities, are described by the kinetic molecular theory of matter (such as pressure, volume, temperature). The idea may be used to explain why matter exists in distinct phases (solid, liquid, and gas), as well as how matter can transform between these phases.

The three states of matter are: As we transition from the solid to the gaseous phase, you'll notice that the distance between atoms or molecules widens.

According to the kinetic molecular theory of matter,

  • Particles that make up matter are continually moving.
  • Every particle has energy, however the amount of energy changes with the temperature of the sample of matter. Thus, whether the material is in a solid, liquid, or gaseous form is determined. The least energetic molecules are those in the solid phase, whereas the most energetic particles are those in the gas phase.
  • The average kinetic energy of the particles in a material may be calculated from its temperature.
  • When the particles' energies are altered, the phase of the particles may vary.
  • Matter atoms are separated by gaps. As a sample of matter transitions from the solid to the liquid and gas phases, the average amount of vacant space between molecules increases.
  • Atoms and molecules interact by attraction forces, which intensify as the particles draw closer to one another. Intermolecular forces are the name for these pulling forces.
<h2>How does kinetic molecular theory affect gases?</h2>

According to the Kinetic Molecular Theory, gas particles collide in an elastic manner and are always in motion. Only absolute temperature directly affects a group of gas particle's average kinetic energy.

Part I of How the Kinetic-Molecular Theory Explains Gas Behavior.

If the volume is kept constant, the faster gas molecules collide with the container walls more frequently and more violently, raising the pressure according to Charles' law.

Two tons of water is pumped into a tank 15 ft. High in 5 minutes. Determine the power output of the pump. (Note: One ton is equa
Semmy [17]

Answer:

200 lb•ft/s

Explanation:

From the question given above, the following data were obtained:

Force (F) = 2 tons

Time (t) = 5 mins

Height (h) = 15 ft

Power (P) =?

Next, we shall convert 2 tons to pound. This can be obtained as follow:

1 ton = 2000 lb

Therefore,

2 tons = 2 × 2000

2 tons = 4000 lb

Next, we shall convert 5 mins to seconds. This can be obtained as follow:

1 min = 60 s

Therefore,

5 mins = 5 × 60

5 mins = 300 s

Finally, we shall determine the power of the pump. This can be obtained as follow:

Force (F) = 4000 lb

Time (t) = 300 s

Height (h) = 15 ft

Power (P) =?

P = F × h / t

P = 4000 × 15 / 300

P = 60000 / 300

P = 200 lb•ft/s

Thus, the power of the pump is 200 lb•ft/s

1. A 25 g rock is placed in a graduated cylinder with water. The volume of the liquid rises from 18.3 mL to 21.4 mL Calculate th
MaRussiya [10]

Answer:

1. \rho=8.06g/cm^3

2. H=10cm

Explanation:

Hello,

1. In this case, since the volume of the rock is obtained via the difference between the volume of the cylinder with the water and the rock and the volume of the cylinder with the water only:

V=21.4mL-18.3mL=3.1mL

Thus, the density turns out:

\rho=\frac{m}{V}=\frac{25g}{3.1cm^3}  \\\\\rho=8.06g/cm^3

2. In this case, given the density and mass of aluminum we can compute its volume as follows:

V=\frac{m}{\rho}=\frac{1080g}{2.7g/cm^3}=400cm^3

Moreover, as the volume is also defined in terms of width, height and length:

V=W*H*L

The height is computed to be:

H=\frac{V}{L*W}=\frac{400cm^3}{5cm*8cm}\\ \\H=10cm

Best regards.
