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.

Answer:
0.78 atm
Explanation:
Applying general gas equation
PV/T= P'V'/T'................ Equation 1
Where P = initial pressure, T = Initial temperature, V = Initial Volume, P' = Final pressure, V' = Final Volume, T' = Final Temperature.
make P' the subject of the equation
P' = PVT'/TV'.............. Equation 2
From the question,
Given: P = 1.00 atm, V = 5.20 L, T = 60°C = (273+60) = 333K, V' = 6.00 L, T' = 27°C = (27+273)K = 300 K
Substitute these values into equation 2
P' = (1×5.2×300)/(333×6)
P' = 1560/1998
P' = 0.78 atm.
Elemental hydrogen (H, element 1), nitrogen (N, element 7), oxygen (O, element 8), fluorine (F, element 9), and chlorine (Cl, element 17) are all gases at room temperature, and are found as diatomic molecules (H2, N2, O2, F2, Cl2).
Answer:
years.
Explanation:
The half-life is the time needed to reduce in 50% the mass of the sample. So, imagine compound A, after its first half-life, it will have 0.5A. After its second half-life, will have 50% of the 0.5A! So, the mass will be 0.25A. So, the percentage of A, is given by:
Where n is the quantitative of half-life. So, for 18.7% of C, or 0.187:
Applying log in both side of the equation:
nlog(0.5) = log(0.187)
-0.301n = -0.728
n = 2.419 half-life
If one half-life is 5,730 yr, than 2.419 will be:
2.419x5730 = 13,860.870 yr
years.
