We consider a spherical air bubble rising through a water tank. The pressurepinside the bubble isequal to its surrounding pressu
DENIUS [597]

The answer is a change in internal energy causes work to be done and heat to flow into the system.  

<u>Explanation:</u>

Boyle's law says, PV=RT

  • Here P represents the pressure, V represents the volume and T represents the temperature. R is a constant. The volume of an ideal gas is inversely proportional to its pressure if the temperature is constant.
  • When a bubble is present in deep water it has water pressure and atmospheric pressure. Then the Volume increases when water pressure raises which is proportional to the depth reduces.
  • But we should not finalize the volume of the bubble will be four-time as great as at the top than the bottom.  if the bottom of the lake is at four atmospheres, the temperature will not be equal to the top.
  • If the bubble travels from the bottom to the top or vice-versa, it's going to lose or gain heat in a way that must be quite hard to measure.

Convert the following to grams, <br> a. 0.100 moles of CO2
Svetlanka [38]
.100 mol CO2 x \frac{44.01 g}{1 mol}
using the values of the periodic you first add the masses of C (12.01g) and O (there are two so it'll be 32.00g). That value will give the mass of 1mole of CO2.


I hate to do this, but

Consider this reaction: 2Al(s) + 3 CuCl2(aq) → 2AlCl3(aq) + 3 Cu(s) If the concentration of CuCl2 drops from 1.000 M to 0.655 M
Yuliya22 [10]

Answer:

r=-0.0115M/s

Explanation:

Hello,

In this case, the rate is computed as:

r=\frac{C_F-C_0}{T_F-T_0}

As the reaction is analyzed during the first 30 seconds, the average rate will be:

r=\frac{0.655M-1.000M}{30s-0s}=-0.0115M/s

Which negative since the cupric chloride is a reagent.

Best regards.
