Answer:

When Logan opens a new bottle of carbonated beverage, the sudden release of pressure causes the beverage to bubble up and overflow. What could Logan do in the future to prevent the next bottle from overflowing when he opens it.

Explanation:

This is an application of Boyle's law.

According to Boyle's law:

the volume of a fixed amount of gas is inversely proportional to its pressure at a constant temperature.

V  \alpha   \frac{1}{P}

So, if pressure reduces all of a sudden, the volume increases and this causes an overflow of the beverage from the bottle.

To avoid this situation, the pressure inside the bottle should not be released at once. The bottle cap should be opened slowly in such a way that opens a little and then close again open a little and then close like that many times if we do, then pressure inside the bottle goes slowly then, the volume will not increase all of a sudden.

Water flows from the bottom of a large tank where the pressure is 100 psig through a pipe to a turbine which produces 5.82 hp. T
Marianna [84]

Explanation:

Bernoulli equation for the flow between bottom of the tank and pipe exit point is as follows.

   \frac{p_{1}}{\gamma} + \frac{V^{2}_{1}}{2g} + z_{1} = \frac{p_{2}}{\gamma} + \frac{V^{2}_{2}}{2g} + z_{2} + h_{f} + h_{t}

    \frac{(100 \times 144)}{62.43} + 0 + h[tex] = [tex]\frac{(50 \times 144)}{(62.43)} + \frac{(70)^{2}}{2(32.2)} + 0 + 40 + 60

                          h = \frac{(50 \times 144)}{(62.43)} + \frac{(70)^{2}}{2(32.2)} + 40 + 60 - \frac{(100 \times 144)}{(62.43)}

                            = 60.76 ft

Hence, formula to calculate theoretical power produced by the turbine is as follows.

                                 P = mgh

                                     = 100 \times 60.76

                                     = 6076 lb.ft/s

                                     = 11.047 hp

Efficiency of the turbine will be as follows.

                \eta_{t} = \frac{P_{actual}}{P_{theoretical}} × 100%

                                = \frac{5.82}{11.047} \times 100%                      

                                = 52.684%

Thus, we can conclude that the efficiency of the turbine is 52.684%.

Which of these substances, when dissolved in water, is a strong electrolyte? which of these substances, when dissolved in water,
Norma-Jean [14]
<span>Option C. It is sodium nitrate because it is a strong electrolyte that comes from a strong acid (HNO3) and a strong base (KOH). It becomes a strong electrolyte when it dissolves in water, its formula is NaNO3, which is a compound that forms nitrate together with potassium nitrate and is obtained by chemical synthesis.</span>

What is the mass of 2.40 moles of magnesium chloride, mgcl2
LiRa [457]

Hey there!

MgCl₂

Find molar mass of magnesium chloride.

Mg: 1 x 24.305

Cl: 2 x 35.453

--------------------  

          95.211 grams

One mole of magnesium chloride has a mass of 95.211 grams.

We have 2.40 moles.

2.40 x 95.211 = 228.5

To 3 sig figs this is 229.

The mass of 2.40 moles of magnesium chloride is 229 grams.

Hope this helps!
