Answer:

7. B.) The transfer of energy by the movement of matter

8. B.) Divegent Boundary

Explanation:

7. Convection currents transfer heat from one place to another by mass motion of a fluid such as water, air or molten rock.

8. The Red Sea formed due to the Arabian plate drifting away from the African plate, which makes it a Divergent Boundary. (Divergent = Move Away)

How many grams of ethylene glycol (c2h6o2 must be added to 1.25 kg of water to produce a solution that freezes at -5.88 ∘c?
e-lub [12.9K]
The freezing point depression is calculated through the equation,
                                    ΔT = (kf)  x m 
where ΔT is the difference in temperature, kf is the freezing point depression constant (1.86°C/m), and m is the molality. Substituting the known values,
                                   5.88 = (1.86)(m)
m is equal to 3.16m

Recall that molality is calculated through the equation,
                                  molality = number of mols / kg of solvent
                                       number of mols = (3.16)(1.25) = 3.95 moles
Then, we multiply the calculated amount in moles with the molar mass of ethylene glycol and the answer would be 244.9 g.

A diesel truck produces 47.5kJ of useful output energy from 125kJ of diesel fuel.what is the truck efficiency?.show the solution
Alex Ar [27]
You have to do a report :
\frac{E_f}{E_i} =  \frac{47,5}{125} = 0,38

So the truck efficiency is 38%.
