Upwelling is a proccess in which warm, nutrient rich water from the deep ocean rises to the surface. TRUE or FALSE.
Virty [35]

The statement about “Upwelling is a process in which warm, nutrient rich water from the deep ocean rises to the surface” is false. It must be the cold, nutrient rich water from the deep ocean that must rise to the surface and replaces warm surface water. The cause of upwelling is when the local wind patterns blow along the northwest coast of South America causing local surface currents to move away. The warm water is then replaced by the deep cold water

Use the fact that to determine how much the pressure must change in order to lower the boiling point of water by a small amount
erma4kov [3.2K]

Complete Question

Use the fact that d\mu=\frac{V}{N}dp-\frac{s}{N}dT to determine how much the pressure must change in order to lower the boiling point of water by a small amount 3.20e-01 K. You may assume that the entropy and density of the liquid and gas are roughly constant for these small changes. You may also assume that the volume per molecule of liquid water is approximately zero compared to that of water vapor, and that water vapor is an ideal gas. Useful constants: Atmospheric pressure is 101300 Pa The boiling point of water at atmospheric pressure is 373.15 K The entropy difference between liquid and gas per kilogram is 6.05e 03 J/kgK The molecular weight of water is 0.018 kg/mol. (a) 0.00e 00 Pa (b) 1.14e 03 Pa (c) 6.85e 26 Pa (d) 4.24e 05 Pa (e) 3.81e 28 Pa

Answer:

Correct option is B

Explanation:

From the question we are told that:

Given Equation d\mu=\frac{V}{N}dp-\frac{s}{N}dT

Change of boiling point \triangle H=3.20e-01 K

Generally the equation for Change in time is mathematically given by

  d\mu=\frac{V}{N}dp-\frac{s}{N}dT

  dp=\frac{s}{v}dT

Where

    s=Entropy\ difference *molar\ weight

    s=6.05*10^3*0.018j/mol.k

And

    V=\frac{RT}{P} (from ideal gas equation)

Therefore

 dp=\frac{Ps}{RT}dT

 dp=\frac{101300*6.05*10^3*0.018}{8.314*373.15}3.20*10^{-1}

 dp=1137.873pa

 dp=1.14e 03 Pa

Therefore correct option is B
