Which factor MOST directly affects the flow of ocean currents?w of ocean currents?

Chemistry

Lynna [10]3 years ago

B)  differences in temperature

Explanation:

The factor that most directly affects the flow of ocean currents is the differences in ocean temperature from one place to another.

Ocean current is the directional movement of the ocean water in its basin.

The main cause of ocean current is differences in temperature.

  • Ocean water on the surface receives direct sunlight.
  • This warms and the surface and decreases their density.
  • When winds blows over them, they cool and sink under their own weight.
  • The less cold water in depths rise to replace them.
  • This exchange of ocean water due to loss and gain of heat cause ocean current.

A sealed piston contains 400 mL of air at standard ambient pressure. The piston is
nydimaria [60]

Answer:

324.24 kPa

Explanation:

Given that;

Initial pressure P1 = 101325 Pa

V1= 400 ml

P2 = ?

V2= 125mL

From Boyle's law;

P1V1 = P2V2

P2 = P1V1/V2

P2= 101325 × 400/125

P2= 324.24 kPa

A sample of 250 g of water are heated from 40°C to 121°C, calculate the amount of heat energy absorbed.
Marysya12 [62]

Answer:

the anwser isn't in the choices

Explanation:

H=MC(change of temp.)

M=mass of water=250g

C=specific heat of water = 4.186 j/g

change in temperature is 121-40= 81

H= 250x4.186x81=84766.5J

1.5 of potassium ioxcide in 150cm^3 of solution
lara [203]

Answer:

Explanation:

I'm not sure what is being asked, not the units of "1.5."  I don't know of potassium "ioxicide."  Was "dioxide" intended?

I'll assume the question is "What is the concentration, in Molar, of 1.5g of potassium dioxide in 150cm^3 of water (150cm^3 is 150 ml).

The molar mass of K2O, potassium dioxide, is 94.2 g/mole.  1.5g is (1.5g/94.2 g/mole) or 0.0159 moles of K2O.  The definition of Molar is moles/liter.  So take the moles of K2O and divide by the liters, which is 0.150L in this case.

(0.0159 moles K2)/0.150 L  = 0.106 M K2O

What are the elements that make up the compound, and what are some properties of these elements?
nekit [7.7K]

Answer: Below (=

Explanation:

The properties of a compound depend not only on which atoms the compound contains, but also on how the atoms are arranged. Atoms of carbon and hydrogen, for example, can combine to form many thousands of different compounds.
